♡ i am still building my first pc ever ♡

[spare sedge]

what about fan rpm

[spring wraith]

what about it

[pearl heath]

Well you can set that to whatever you want so

What you're looking for is a noise normalised test, which GamersNexus does for their reviews

[spare sedge]

with pwm

[pearl heath]

Or DC control

[spare sedge]

still dont understand dc

only dc ik is ac to dc

[pearl heath]

That is electrical theory, can go on a Wikipedia crawl if you wanna

But understanding of how DC control fans is just
Less voltage means slower speed

[pearl heath]

PWM sends full voltage always but chopped up so that the fan only gets full power sometimes and regulates speed like that

[pearl heath]

All of those will be horrifically loud
Those are for servers, or are stock coolers in disguise

[spare sedge]

i remember learning this

[spare sedge]

they dont seem loud

only 35 db

[pearl heath]

Those are cherry picked numbers

[spare sedge]

where do the rads go?

[pearl heath]

In the case

[spare sedge]

where in the case

[pearl heath]

Where they fit
Refer to a manual to see on a per case basis

[spare sedge]

that doesnt really help me tho

i dont have a manual

does the hot air from the rad blow into the case?

[pearl heath]

Yes and no

Depends on how you set up the fans

[spare sedge]

how so

[pearl heath]

Well
Orient the fans to blow air into the case
Orient the fans to blow air out of the case

[spare sedge]

so they blow hot air into the case and outside of the case at the same time?

[pearl heath]

Depends on how you orient them

[spare sedge]

how can i orient them to do this

[pearl heath]

Looking at them and seeing which way the air flows when they're on

[spare sedge]

idk what to look for

which way does the air flow

[pearl heath]

There are guides available for figuring that out

[spare sedge]

so you dont know

[pearl heath]

I do know

[spare sedge]

then what was the point

[pearl heath]

But I don't want to keep spoonfeeding information

There is a point where you really gotta do your own research

[spare sedge]

look if you arent going to help. then dont bother

[pearl heath]

Come here for pointers, and more esoteric topics

[spare sedge]

i will just try again tomorrow

forget it

[pearl heath]

This thread has 6043 posts as of this message, we try to help so much but there are so many damn questions whose answer is a simple Google away
We help, but with the weird things
Like explaining why quad DIMM RAM setups are bad, or like how immersion cooling is actually horrible for your components and sanity
We help with putting together a parts list for a set budget and maximising the performance for the price
But we cannot help with googling what an IHS is

[spare sedge]

if you are here to drive home your points instead of helping me, then just leave me alone.

who cares if the post has that many messages. it wasnt even because of me.

it literally doesnt matter how many messages it has

im already googling all night long

im already watching youtube in the background for 10 hours straight afterwork with no sleep

the least you can do. is answer a simple question. or watch someone else do it for you.

if the answer is go somewhere else, we cant help you. then im not going to learn. i came here for help with research

the research of pc building is oversaturated with its ownself

explaining quad ram and immersion cooling are perfectly understandable things to go over. i can't believe there is a human on this earth who thinks it's not important

it takes 2 secs to say what you meant when you say ihs. it doesnt matter if everyone else here knows what you meant by ihs. because I didnt know.

[orchid gate]

No no it forces air out

Usually for exhaust purposes

[spare sedge]

so aio has no air?

[orchid gate]

Nope.

Fans are just an escape vent for heat

After all it’s purpose is to cool your system not trap heat in one part of it (without fans hot coolant would just circulate ad infinitum in the AIO loop)

[spare sedge]

on pcpp builds i always see people make these builds and they have all the colorful fans at the bottom

[orchid gate]

Actually I need to read up on this, in my mind there are two ways this could theoretically work

[spare sedge]

how are case fans separate from the cpu cooler or even the case

i thought the fans came with the case

[orchid gate]

Nvm one of them is pointless, I was thinking the fans could cool the coolant directly by taking in cold air

But then what’s the point lol at first, when it’s not boiling hot

[orchid gate]

You need extra fans

To pass air out of the case or take it in

AIO and CPU cooler alone too weak to do both

[spare sedge]

ik cases will have rgb fans vertically

[orchid gate]

try blowing through your plumbing system

See how much air comes out the other end

[spare sedge]

can you put the aio there instead

[orchid gate]

?

You buy those

They aren’t stock

[spare sedge]

thats what i meant

[orchid gate]

you can place them anywhere on the border

Just depends on how you want the air to flow

[spare sedge]

but im asking can i place my aio there to shoot out the hot air from the case

[orchid gate]

Better if you mount it on top, so you or your monitor aren’t blasted with hot air plus naturally there’s more space overhead for the air to diffuse, not many obstacles above

ATX case should make this much easier

.

If you like inferring information, for cooling perf you should look at reviews on TechPowerUp (website) and Gamers Nexus (both website and YouTube channel)

[spring wraith]

^ you can safely disregard any fan ratings not done by a third party

cfm measurements are useless

as are static pressure ones iirc

[spare sedge]

whats cfm

[spring wraith]

basically a measurement of how much air is drawn / pushed by fans

but its super inconsistent between manufacturers

[spare sedge]

is it cubic feet per minute?

[spring wraith]

yes

[orchid gate]

Per minute seems like a wild ballpark to measure

[orchid gate]

You seem like you really need this PC to the point of insurance in the form of adequate research

Rushing for some reason?

just noticeable that’s all

[vast geyser]

whaaaaaaaaaaat no...

[grave spade]

What do we have now

[vale prairie]

Msi Suprim X watercooled and 7950x3d I think

And an x670e mobo

And maybe an aio with a screen

[vast geyser]

could just buy a d41 screen and you have a screen and a nice case so you dont need an aio screen

[viscid plover]

Hey

This is for dream

[brave brook]

if she goes itx, we must not let her get an x670 itx motherboard

[viscid plover]

Many problems with it?

[brave brook]

a waste of money because itx doesnt have the space for all the expansion available with x670

[viscid plover]

I understand.

[brave brook]

but knowing dream, she'll want "the best" which is x670, so she'll want to spend a bunch of extra money for no actual reason

[viscid plover]

Btw itx mini version and atx standard version?

Sry I'm only used to atx mid towers

[brave brook]

yes, itx only has one pcie slot. hence why x670 is useless

[teal pond]

why does she want itx?

[brave brook]

shes debating it, for vanlife

[teal pond]

ohh ok

[open iris]

Itx looks cute

[vale prairie]

Put a dual tower cooler on an itx mobo lmao it’s amazing

[viscid plover]

@brave brook @orchid gate grel told me I'm trolling or what after I switched from i9 13900k to i713700k. Then he proceeded to go offline and not explain reasoning to me. Did I do something wrong?

[vale prairie]

You did a lot wrong my friend

[open iris]

you downgraded your cpu for what?? 🤔

[viscid plover]

For a 3% gaming diff and a 20% workstation difference? Imma let u know temps are 60C for both cpu and gpu while ultra at any game 2k resolution

[vale prairie]

If your getting a cpu for gaming get the 7800x3d

[viscid plover]

No overheating plus no bottleneck

[viscid plover]

Not an amd guy sry

[open iris]

overheating sounds like a cooling problem, the bottleneck part is just dumb

[viscid plover]

I7 13700k

[vale prairie]

LS/T 720 will fix all your problems

[viscid plover]

Does it matter tho? Very small diff between these two

Brother I was scared

[open iris]

i mean no it doesnt

[viscid plover]

Cause I read bottleneck problems

[open iris]

both are fine

[viscid plover]

I'd pair i9 13900k with 4090

[open iris]

the way people talk about bottlenecks is dumb

because no matter what pair of cpu and gpu you have

theres always a "Bottleneck"

[viscid plover]

True that concept is misunderstood. All I know is that on many sites it was saying 4080 too weak for i9

[open iris]

that doesnt even make sense because that fully depends on what your doing

what game it is

[viscid plover]

Pubg ultra

[open iris]

what your workload is

[viscid plover]

Rocket league ultra

Softwares: autocad, revit, sony Vegas pro 9 and 64 google chrome tabs

Workload on gpu 100%

Cpu 20%

I mistaken utilization of gpu with heating issues

Big mistake

100% utilization means the gpu is allocating full force to game to provide best frames

[spare sedge]

omg the teal yellow pink is my favorite

[spare sedge]

the ram is good too

ik im not doing immersion

ik im not doing stock

probably not going for a good fan at least not for the cpu.

might have to do double aios

ig i go open loop. i would still have to go 2 to 3 rads

im listening to videos while i work

[open iris]

do you think you will go itx?

[spare sedge]

its hard to say.

glass tubing is also not good for vanlife

but other options might be okay

i know about the fittings

and the tubing

and tubing materials

[orchid gate]

Bro I’m a student i didn’t purchase permanent residency here

[spare sedge]

and the coolant dye

[orchid gate]

Although yes it was an awkward moment

[open iris]

ngl an matx case makes more sense for you if you wanna watercool

still pretty small but you actually have space for shit

[spare sedge]

there might have been a trolling situation in the server history and now its just a pc builder thing where no one knows if you are or not

[orchid gate]

ATX should be fine..

Just transport fears are there, like too much space for stuff to wriggle about or sag and such

[spare sedge]

i might do matx

or just atx

is it possible to even buy mini dtx anymore?

ik each part needs at least a 120 mm rad

[orchid gate]

Keep the box for your case once it arrives, if you’re driving then stick it in the box (pray it’s not going to be too heavy, will exceed 5kg maybe) and secure it high above

[spare sedge]

but if overclocking then at least 240 mm

[spare sedge]

i will i saw they use it to adsemble

[orchid gate]

Probably here I’ll point out the weight of these things

[spare sedge]

is this possible

[orchid gate]

Motherboard alone can be 3kg

[orchid gate]

Wut

I mean the PC case will come with a box

how else would it ship or be delivered

personally I don’t like any markings on my cases from rough handling

(And some components need to be assembled post delivery, like fans if you buy a Lian Li or Fractal case which comes with them)

[spare sedge]

But is it practical to take the pc after its built and throw it in the box with all the parts built or do you mean something else

[orchid gate]

You can lift it

Then lower it into the box

[spare sedge]

im doing extensive research into the vanlife part

causr it doesnt have to be just vanlife

its also cops or truckers

[orchid gate]

Nani

[spare sedge]

cops have armor on theirs

[orchid gate]

what

[spare sedge]

but truckers use bungie cords

[orchid gate]

oh types of van?

[brave brook]

An atx build with an AIO and a gpu support bracket (unless you use a water cooled 4090. but even then, you might still want one) will most likely be secure enough for vanlife

[spare sedge]

but it would also seem from the video i posted. that you dont need those to keep your pv from hitting a curb or something

[orchid gate]

I think I know what you’re talking about

But I wouldn’t have piece of mind leaving it “in the open”

[spare sedge]

im talking about ways truckers put a pc in their truck

or ways cops put a laptop in their copcar

[spare sedge]

so there wouldnt be windows

but i dont plan on relying on its own weight from falling over

[orchid gate]

Correction don’t lift the PC (stupid way), just cover it with the box by flipping it upside down and lowering that onto the PC exterior

[spare sedge]

im a great driver. but a hard brake is sometimes necessary to avoid accidents.

im really only worried about hard brakes and potholes

[orchid gate]

If this were a reg SUV or any car with space below the seating, I’d keep the PC on the floor

[orchid gate]

It is what I meant, but better and less tiring way is just to cover the PC with the box (lift the box and lower the open end onto and over PC)

[open iris]

put the pc in the seat next to you and put on the seatbelt

[orchid gate]

Yes but that would still require lifting ;p

Anybody got an approximate measure for the weight of an average ATX PC?

[orchid gate]

Have you decided on a case yet?

A good mATX case would be the ASUS Prime AP201

I’ll need it to calculate how heavy the PC will be

[viscid plover]

I have LT720 deepcool aio cooler. What is LS/T 720?

[orchid gate]

LS or LT afaik

[viscid plover]

Msy I ask what diff is there?

[orchid gate]

Search online

Use Google

[viscid plover]

I can't get over how good it looks omg 😍

What cpu aio cooler with biggest lcd screen would u all recommend me for nicer looks while I insert gifs in it?

I'm considering that

[open iris]

the average pc is probably 15-25kg anyway ~

[orchid gate]

Seems a little heavy to me

[open iris]

most the weight is just the case though

[orchid gate]

and that’s what I’m finding out

it would vary with form factor

[spare sedge]

im guessing lighter will mean less damage on bumps etc

[viscid plover]

I agree. Not the first time I noticed someone telling me my build is troll.

[open iris]

eh lighter cases probably use weaker materials unless they are just lighter cause of size

[viscid plover]

Idk what u mean by that but ya mby provide a clearer explication?

[open iris]

my case is 9kg turns out

[viscid plover]

Why is my cpu decision swap troll

That's all I want to know

[spare sedge]

it is going to be like that. but i wouldnt do below seating. why do that?

[open iris]

i mean surely you can just have a box with plentiful foam to put the pc in when moving it

[spare sedge]

moving will probably be an everyday thing tho

[open iris]

reuse the box

[spare sedge]

box shielding might be a good idea for longer drives maybe

[open iris]

also damn that might be rough if you go with the aio gpu

ideally youd take out the gpu everytime you transport the pc

so it doesnt destroy the slot

[spare sedge]

i think thats only necessary if i dont have a gpu kickstand

[brave brook]

what?

an aio gpu is ideal on an atx build for vanlife

because the majority of the weight is screwed securly to the case

[open iris]

gpu kickstand would solve it

the gpu would still move around the tubing aint solid

[brave brook]

its still much less weight on the pcie slot and back pcie slot covers

but with a support bracket, every gpu is pretty safe to move around

[open iris]

the problem is only partly the weight its mostly the movement

[orchid gate]

If the case can be strapped down then problem solved either way

No wobble

That remains to be decided however, certain if this (tying down to a pickup truck) happens

[brave brook]

its mostly the weight that causes the movement to break things

but either way, a gpu support bracket would definitely be recommended

[orchid gate]

Nothing she can’t afford

[brave brook]

yeah

[open iris]

well no cause the gpu can still move cause yknow physics

[brave brook]

should be a big piece of steel because why not

[orchid gate]

Ik, impact waves and such from speed bumps or potholes

could shift some smaller component within

But I’m pretty sure the tubing connected to the radiator and GPU isn’t that fragile

[brave brook]

here are some options
https://www.guidingtech.com/best-gpu-support-brackets/

[brave brook]

no its not, and its flexible anyway

[spare sedge]

im not worried about strapping it down or mounting it lol

im worried about potholes damaging the parts

[orchid gate]

If everything is attached securely during construction, it should be a solid body overall

Nothing individually should exhibit movement

[brave brook]

personally, think a vertical support bracket would be better than a horizontal one, as the "support point" is closer to the end of the gpu

[orchid gate]

So just make sure you firmly slot in the GPU, hear the click from a ram slot

[spare sedge]

even if it is mounted or strapped down.

a stiff pc will take the shock

im interested in shock abdorber solutions

[orchid gate]

But everything in the PC ok isn’t designed to withstand an earthquake of 9.0 magnitude , but of very dense construction

[spare sedge]

truckers usually do bungie cords or something on the bottom

[brave brook]

an aio for the cpu, an aio gpu, and a gpu support bracket will secure virtually every "fragile" component

[spare sedge]

i could maybe do memory foam

[orchid gate]

^ don’t have to invest in foam kassy

[spare sedge]

underneath with it mounted

[brave brook]

hang it from the ceiling with a case that has handles

[brave brook]

why not

that is the safest way of mounting it

[spare sedge]

omg is this possible?

[orchid gate]

Wrong interpretation, I did mean to support your idea

And not the need for foam

[orchid gate]

Uhm 💀

[brave brook]

ig you replied to the wrong message lol

[orchid gate]

Didn’t finish my sentence

[brave brook]

yes

[orchid gate]

What case is that

[brave brook]

asus tuf gaming gt501

[orchid gate]

And I wouldn’t want John cenas dumbbells hanging freely above my noggin

[brave brook]

true, itd be best to also put bungie cords below it as well

[spare sedge]

is this just a normal case

[brave brook]

normal as in just a case with handles added? yes

its not really that special. the asus tuf series just usually has carrying handles

[dusk sierra]

It stands for small form factor its builds with cases below 20 litre volume

[brave brook]

i knew it stood fro small form factor, i didnt know there was a certain litre volume

[brave brook]

its also one of the most popular cases with handles

[spare sedge]

what are the handles for

[brave brook]

Carrying it…really whatever you want

[spare sedge]

what was your suggestion tho

[vast geyser]

wait

r u really considering a loop

[spare sedge]

aio or open loop yes

[vast geyser]

wtf is an open loop

oh its a custom loop

why would you torture yourself with one

[spare sedge]

https://youtu.be/DeBxEb_kcxE

[vast geyser]

i sense 1 issue

teeny tiny

[spare sedge]

whats up

[vast geyser]

its your first pc, and thats wildly difficult for not that much more performance, or at all actually

[spare sedge]

not about performance

[vast geyser]

isnt the goal supposed to be to use as little power as possible in a van

[vast geyser]

what is it about then? looks?

[spare sedge]

yeah honestly

pink tubing would be so fucking cute

[vast geyser]

yeah, but gl cutting it, making sure it fits, buying the right stuff

[lavish nexus]

Have you still not started building the pc

Or just waiting on shit

If you want cute and don’t mind going amd….yeston makes a pretty cool looking 7900 xtx

And they make several other really cool looking girly themed gpus

[heavy linden]

they arent girly themed, its for us cultured peoples

[lavish nexus]

[viscid plover]

I would not put tubes in a van

[open iris]

We need more colourful options in general ngl

Give me the full rainbow as options

Im tired of fucking all white or black

[slender basin]

every build seems to be all white or black now

with little to no personalization

well I guess build/setup

[open iris]

Yeah so true

my pc is white and black

In my defense though I'm planning to do it up with a bunch of art painted on acrylic

[teal pond]

dream idk if this matters much but there was a guy who tested if a pc could survive dropping from a certain height

it was from a roof and it still booted but it was smashed

[brave brook]

Do an AIO. It’s the most secure cooling for vanlife

[brave brook]

The problem is, the sales volume of even white is much lower than black, so it’s not feasible

[open iris]

We need better propaganda for coloured parts you see

[brave brook]

For the manufacturers to make no money on them?

[spare sedge]

what are "headers" and splitters too ig

[brave brook]

splitters split one connection into 2 or more. a header (on a motherboard) is how front panel usb, fans, and front panel audio are connected to the motherboard

[spare sedge]

so splitter is general for any kind

a little lost on headers still tho

ik what the io shield is

[brave brook]

Well, a header is also usually a set of pins soldered to a motherboard or other pcb that allows wires to be connected and disconnected at will

[spare sedge]

so connectors directly on the mb

so like 3 pin or 4 pin fans connect to the mb header?

[brave brook]

yep

[spare sedge]

is the header only for mbs or is it also general like splitters

[brave brook]

it is not a splitter

[spare sedge]

no i mean

is it a general term like how splitter is a general term

[brave brook]

oh

yeah its general

[spare sedge]

so what other kinds of headers are there that are good to know? i know about the mb header. its usually along the ridge of the board

but you can have some sticking out orthogonal to the board

im guessing

[brave brook]

Yes

[brave brook]

Uhh you should know the types of headers, usb 2, usb 3, usb 3 type c, fan, hd audio, etc

And what they look like

[orchid gate]

These allow the I/O to function

[spare sedge]

no i meant like do other parts have headers

besides the mb

[orchid gate]

Don’t think so

[spare sedge]

oh so when someone says header. its ALWAYS the mb

[orchid gate]

Yes

[spare sedge]

okii

[orchid gate]

unless

It’s a programming term too, like what you see when you look at the “title” of a browser tab

[spare sedge]

thats okay

so noise is just a biproduct of the rpms

the rad is like the capacity

so like with ram

[orchid gate]

Nani

[spare sedge]

a 420 mm rad doesnt mean it will cool faster

its all about the aio fan speed. the rpm.

[orchid gate]

No way to measure cooling capacity/ability unless you read a chart or test temp performance

[spare sedge]

the rpm is the actual cooling power

[orchid gate]

no

It’s rounds per minute

How fast it spins.

Smaller fans spin faster to match perf of larger ones

it’s not good to have them spinning extremely quickly

So a 180mm fan (for cases that are massive like the fractal torrent) might max at 1200RPM, but a 120mm might max out at 1800RPM

it’s not like an HDD where faster spinning means better performance (no comparison anyway, HDDs are fast af at 7200RPM)

[spare sedge]

yeah exactly

a larger fan wont have as many rpms

for the same performance

[orchid gate]

Correct

So it’s more efficient at moving air

Better cooling capability

[spare sedge]

is there gaming fans lmao

[orchid gate]

no need

[spare sedge]

what about workstation fans

[orchid gate]

All PCs will look gamer-y if configured like todays

nope

Just case fans.

workstations use noctua for instance as well as any rich gamer building idle machines

[spare sedge]

rpm is still a good indicator for aios tho

[orchid gate]

Oh I’ll need to research that

thought you meant case fans or tower coolers

[spare sedge]

because the width can't vary that much, but obviously if the width is max width and you compare the width to the least width, the delta performance is the % error

cause the length is determined if you only compare within the rad size

[orchid gate]

What is that

[spare sedge]

like 120 mm

[orchid gate]

If it helps ik most radiator fans are this size

Single fan AIOs exist

For ITX; but let’s not be distracted

[spare sedge]

basically what im saying is i can look at only 120 mm rads with the highest rpms to get a pretty good idea of the market. because the width range wont have a major impact on cooling performance because its relatively minor

[spare sedge]

sly, but remember fans are squares not rectangles.

[orchid gate]

usually it starts at 240mm, gets to 360mm, large ones can be 420mm (140mm each fan)

[orchid gate]

Yes that’s true

So they are square shaped

[spare sedge]

meaning if only 1 fan is on a 120mm aio, the rpms are comparable and if it has 1 fan, you will notice.

[spare sedge]

what are the best aios on the market?

https://pcpartpicker.com/product/V2JwrH/corsair-h100i-77-cfm-liquid-cpu-cooler-h100i how about this one

[orchid gate]

Lemme search

[brave brook]

Yeah, but it’s not just “mb headers” that’s my point. There are different types that you should know

[spare sedge]

https://pcpartpicker.com/product/2zQypg/corsair-h80i-77-cfm-liquid-cpu-cooler-h80i

i meant this one

[orchid gate]

Why single fan

[spare sedge]

what are the different types?

[brave brook]

Ew no, not a 120mm AIO

An actual waste of money

[orchid gate]

#1139391773253316608 message

[brave brook]

A single tower air cooler will perform as good or better at significantly less price

[spare sedge]

i already know these. these dont matter

[orchid gate]

Those are headers

[brave brook]

Wdym don’t matter

[orchid gate]

On the top and bottom edge of mobo

want the images, you mean?

[spare sedge]

i just wanted to know WHAT a header was. it describes the mb.

like a cpu doesnt have a header

a gpu doesnt have a header

[brave brook]

You asked what headers you should know, so I told you

[spare sedge]

ram doesnt have a header

coolers dont have a header.

cases dont have a header

[orchid gate]

The ones mentioned do

[brave brook]

Not unless you count cpu fan headers, or AIO pump headers

[spare sedge]

those arent headers

wtfdym

[orchid gate]

Headers are like expansion slots.

[brave brook]

Front panel connectors could be

[orchid gate]

They function because they’re plugged into one

[brave brook]

Yes they are

[orchid gate]

lemme show you what headers look like

[spare sedge]

thats literally not what i was told

[brave brook]

What were you told

[orchid gate]

Well think about it this way. USB doesn’t have a slot, AIOs don’t have a slot

[spare sedge]

what is a front panel?

[brave brook]

This

It’s usb poets and power switch(s) on the front of the case

[orchid gate]

These are headers, the black rectangles with pins sticking out

Actually some of those could be for PSU

Bottom is header though def

[brave brook]

Just the top right

[orchid gate]

What’s the bottom for

[brave brook]

And I wouldn’t really call sata data connectors a header

[orchid gate]

The ports on the outside of a case.

[brave brook]

What bottom

[orchid gate]

Bottom two circles

which connectors are those

[brave brook]

The right is sata for 2.5” ssds and hdds

[orchid gate]

@spare sedge have you seen/scrutinised any images of what you want?

Past journalism shots and demos

[brave brook]

Bottom left is a mix of fan, usb, and maybe thunderbolt?

[orchid gate]

So those are also headers then

[brave brook]

It’s too blurry

[orchid gate]

Mb

Phone resolution

[brave brook]

Yes, any bare pins sticking out of the motherboard are headers

Well, certain sets of them

[orchid gate]

I should link a really thorough PC build guide here

[brave brook]

Internal usb type c (typically usb 3.1/3.1gen2 or 10Gbps usb)

[brave brook]

Yes

[orchid gate]

So kassy gets a good idea of what everything looks like and is called

I’ll be back in a min

https://youtu.be/IdrdT9F14FE

Skip to 11:20, or just to “case cable installation”

That’s when the headers are plugged in, gives you a macro shot

Keep this safe @spare sedge

This guy does builds in popular cases and highlights the quirks of each

[spare sedge]

this is just a build guide lol

[open iris]

Did you come close to deciding a cooler

[spare sedge]

i kind of dont know any good ones

or any good examples

or the market at all

i dont know how to distinguish 2 coolers really besides looking at the fan size and rpm speed and the rad size

idk what size rad i should go with

jtc says to go 120 mm unless you want to oc. 240 mm. they have 280 mm which is a weird size but it seems to fit sff based off the video i posted.

[orchid gate]

Yes but it shows you what everything looks like

If you listen to his words he points out what they are

Unless his accent is too heavy, then I can “translate” a few phrases

[orchid gate]

Colour scheme/CPU attachment thing can be completely different

Like EK Basic 360 AIO has a square block attached to CPU, Lian Li Galahad has a round one

logo is usually displayed on them

[spare sedge]

does square or round matter

i have usually only seen aio with screens on the block

[open iris]

120s suck and arent worth the money

240 is min size you should get really

[spare sedge]

why / how

[open iris]

unless you like literally cant fit it and all you care about is looks

rads just too small to be that effective

[spare sedge]

i also hear that you should try to fill all the leftover space you can with p much just radiators

[open iris]

yeah bigger rad the better

360s are usually ideal

[spare sedge]

so if your case can fit a 280 mm instead of a 240, then might as well do the 280

[open iris]

wont work if you go itx though probably

[spare sedge]

after 360 there is 420 mm

and i think those are the only options

[orchid gate]

Haven’t seen many 420mm out there

[spare sedge]

i think sff can only do 280 mm max tho but im not sure

[orchid gate]

Save for the arctic liquid freezer II

[orchid gate]

Say what 💀

[orchid gate]

someone remind me how big the AIO supplied with the cooler master NR200P Max is again

I think it’s about that size could be wrong

[spare sedge]

seems like only 15 420 mm rads are on the market right now

[orchid gate]

Can’t see the image

[spare sedge]

so should i prioritize rad size or aio fan rpm?

[open iris]

420 is just kinda too big for a lot of cases

rad size

[orchid gate]

I’m on a train anyway so poor reception is to blame

[spare sedge]

will 420mm fit an atx case?

[orchid gate]

Depends what ATX case

[open iris]

depends on the case

[orchid gate]

the constantly mentioned Fractal Torrent which fits server stuff? Yes

[spare sedge]

so it fits some of them

[orchid gate]

This especially well

[spare sedge]

alr

[orchid gate]

I mean considering the GPU slot has about 450mm headroom

[spare sedge]

jtc says to prioritize rpms

cause you dont want a rad with low rpms

what is headroom?

[open iris]

i mean true but priortize that within sizes

[orchid gate]

Total space that fits stuff lol

General English term

[spare sedge]

okay so rpm second not noise?

[open iris]

if you want max performance yeah

[spare sedge]

and then if you want min footprint do noise 2nd or first maybe

[orchid gate]

Look at the chart, liquid freezer is “slower” than the Corsair mabob below it

[open iris]

yeah

[orchid gate]

But it’s quieter

Than all the others

[spare sedge]

any tips on noise

[orchid gate]

well use a mesh side panel for your PC case unless your fans are struggling to pull air in

[orchid gate]

install the dust filters provided with the case

If you have fans on the bottom and plan to place the pc on carpet or in a corner

[open iris]

fanless pc

[spare sedge]

yeah but you said 450 mm headroom like thats significant but i have no idea what that means or how you would know at all

[orchid gate]

I didn’t say you were stupid or anything

It’s a massive case yes indeed

I’m not kidding at all

[spare sedge]

all i know is that it is a clearance sort of space inside of the case and that it is 450mm and that it is near the gpu

[spare sedge]

is fanless good?

[spare sedge]

im p sure these are fans tho

[orchid gate]

Nah

[spare sedge]

nah what

[orchid gate]

Nvm

[open iris]

not really

0 sound at all from a pc is pretty funny though

[orchid gate]

Part compatibility chart for the fractal torrent

downside is the case itself is 11kg or like 20 pounds in weight

So lifting this thing to move it constantly would be a silly idea if you add on the fact the motherboard and GPU are another 5kg or so

So make that 33 pounds total for a build in it

.

Comes with a fan hub (so you don’t have to worry about headers for the case fans), very good stock fans that are 180mm and 140mm (not just compared to other stock but aftermarket too), a GPU support bracket, and cable management grooves/Velcro straps on the backside

And you can use 420mm AIOs with this

[spare sedge]

wait are you saying its slower because the rpm lows are slightly lower by about 300 rpms?

[orchid gate]

I’m assuming that’s what it means

Point is noise performance is often valued over RPMs when the product isn’t a shitty one

[spare sedge]

wait are you saying these are actually fanless?? i thought these were aios. what are they? how does a fanless cooler work??

i thought you were joking

[open iris]

either relying on the rooms air if your entire pc is fanless or your case fans making good enough airflow

[spare sedge]

i dont plan on moving the pc around. like carrying it into coffee shops or something? nah not me.

would be cool with an itx build and like some kind of portable monitor tho

[open iris]

fanless pc's really funny they are just all heatsink

[spare sedge]

what are these then?

[orchid gate]

Side note but are you interested in ATX again

[spare sedge]

WHAT

[open iris]

just heatsinks

[spare sedge]

lmao

theres no fucking way

is that really a thing

[orchid gate]

^

[spare sedge]

how would the heatsinks cool off??? that would be a hot af pc

[orchid gate]

Fractal torrent will just be a document crushing paperweight

[spare sedge]

worse than stock probably

[orchid gate]

So open side panel

And hope the environment is cool enough to absorb heat

[open iris]

like i said the air from your case fans passing through the heatsink

or your room if your entire pc has no fans

[spare sedge]

so a heatsink setup could work if you are gaming outside in the woods at night

during the winter

or fall

[open iris]

basically lmao

[spare sedge]

lmaoo

that would be so cool tbh

[open iris]

look at this one gn covered https://www.youtube.com/watch?v=ZVpO4Owmgko

who needs a heatsink in a pc when your pc can be the heatsink

but yeah you pretty much have to like undervolt all your stuff

and have a pretty cool room

[vast geyser]

wait so were talking coolers?

apparently the frozen notte is really good (i have no proof of this)
the lt series is the best
then LF2 and stuff

[spare sedge]

gamer nexus kind of scary lately

that one video thumbnail 😬

[spare sedge]

wait so all aios have 2 tubes?

[vast geyser]

i think so

[open iris]

the water needs to go in and out

[spare sedge]

i thought it went in and out in the same tube

an in tube and an out tube makes much more sense

[vast geyser]

yep

[spare sedge]

aios also have less clearance issues since the block is small

[open iris]

do you mean compared to custom looping

or tower coolers

[spare sedge]

air

but i guess open loop has even less clearance issues since you can just do whatever the fuck you want

[open iris]

the downside with them though is just the amount of space they take up in general

[spare sedge]

i wanna do open loop but its very DIY and they still use 2 - 3 rads

rads are just filler space and you should max it

[open iris]

i really just dont think its feasible for a first build

[spare sedge]

what are the big cooler brands

[open iris]

more so if youre doing itx

[spare sedge]

nothing like cooler wars going on right? like amd and intel

[spare sedge]

its feasible it doesnt matter if i am new

the only reason people dont recommend it is because its not as fun for that first time experience. its like a chore unless you already know you find that sort of thing as fun.

[open iris]

no its just actually difficult and easy to mess up

[spare sedge]

not really.

you just bend the tubing

check for leaks

buy all the little parts

[open iris]

[spare sedge]

ik all the parts

the res has the pump built in

then its just the block and the rads

and the tubing

you can do soft tubing

which would be fine for vanlife

even immersion cooling has a lid for the tank.

and back in the 80s people were doing immersion cooling for testing.

without the lid

the liquid amounts are completely fine in aio and open loop

the res can be turned upside down and its fine. it doesnt leak as long as youve tested for leaks but it does cause problems with the pump and rads apparently

soft tubing doesnt even need as much bending

and as far as i am aware all you do for bending is use heat

theres 90 degree bends and 180 degree bends which are the hardest

but its really just patience and time consuming which i wouldnt mind

the only problem is if you move things around in your case you might need to redo the tubing

and then theres fittings and cutting the tubing

costs about $1000 for a full system i think

cant really find a clear answer

and $1000 isnt even bad like

immersion is only $2500

im already spending $200 on a better aio for the gpu

so then the cpu cooler +$200 we will see if the exceeds the $1000 which it shouldnt

and then im pretty sure you dont even need case fans if you do open loop

and case fans get expensive

[open iris]

dream you can describe the process of doings things in a simple way very easily but doesnt mean you can actually succeed in doing it but if youre confident i wont stop you itll be fun it see and yes you still need case fans

aslo can just use the ones that come with the case

[spare sedge]

i thought i saw a open loop itx build without case fans

[open iris]

im sure that exists doesnt mean its optimal

[vast geyser]

you need fans

[spare sedge]

yeah for other parts

like mb

[vast geyser]

idk how good idea it would be to have bunch of tubing and stuff in a van. that moves around a lot.

1 speedbump and its over

[brave brook]

That’s why I keep saying use an AIO

[spare sedge]

a new microcenter is opening in indianopolis and they have grand opening deals

i live by that one

but itd be the farthest one

wow i might do that

how did i get so lucky

its only a 3 h drive

detroit mc is 1 h

columbus mc is 2 h

[vast geyser]

now i will triangulate your location

[spare sedge]

lmao

it was in the previous post

[vast geyser]

oh thats sick

[spare sedge]

so if i want best price / perf i should go to this indianopolis if they have the deals on the parts i want huh

[vast geyser]

youre way past price / perf

[spare sedge]

yeah but obviously if theres a deal

i should take it

ive never been to mc or indianapolis either

so itd be an experience

[vast geyser]

oh for sure

might be worth a trip just cause

[spare sedge]

especially if i can find a guy to drive me

is microcenter cheaper though?

like usually without grand opening

[vast geyser]

from what i noticed, not really

its usually just free stuff sometimes and GREAT bundles

like there was a 12900k + z690 + 32gb of ddr5 for $400

[spare sedge]

so if no deal no point outside of just getting your parts same day

[spare sedge]

that's insane

i almost dont believe you

[open iris]

Microcentre often do ridiculous in store only deals to get people going in

[spare sedge]

thats like last gen top cpu with a top board with whatever ram

[vast geyser]

pretty darn decent z690

[spare sedge]

are you able to see the in store deals before commiting to the drive

[open iris]

Idk I'm not American

[spare sedge]

wtffff

[vast geyser]

i mean, yeah

[open iris]

Sometimes they just do crazu shit though

Likr free ssds for any purchase in store was one iirc

[spare sedge]

omfgggg

Tthatsss insanenee

grand opening is probably more insane

[open iris]

They were sata ssds it's not like top spec

Free is free though

[vast geyser]

https://www.microcenter.com/product/5006544/intel-core-i9-12900k,-gigabyte-z690-aorus-elite-ax-ddr5,-gskill-ripjaws-s5-32gb-kit-ddr5-6000,-computer-build-bundle

[vast geyser]

like honestly, you can probably just grab that and not worry about anything

[spare sedge]

wait is that one going on right now

im kind of a deal junkie ngl

[open iris]

If i ever plan to go on holiday to America though fuck it microcentre will be a tourist spot

[spare sedge]

ironically

[vast geyser]

yeah you can check the locations

in store only

[spare sedge]

each location might have different stuff going on too

[vast geyser]

https://www.microcenter.com/product/5006545/amd-ryzen-9-7950x3d,-asus-b650e-f-rog-strix-gaming-wifi,-gskill-flare-x5-series-kit-64gb-ddr5-6000,-computer-build-bundle

basically everything youre looking for

[spare sedge]

i wonder if i could get the bundle deal but pay the difference on alt mb or alt ram

that ram isnt a bad choice tho. its a ripjaws so no flare.

[vast geyser]

nope

idk what you would even replace

its a darn good b650e
decent ram
and the fastest cpu

[spare sedge]

yeah i mean the ram is like #3

cpu is like #2 gaming and #4 productivity

[vast geyser]

its an x3d chip so doesnt really matter

i mean the ram

[spare sedge]

amd likes tighter timings tho

if i do the suprim x liquid. that's only $2500

[vast geyser]

you can try and tighten them yourself. but ram doesnt really affect the x3d chips

[spare sedge]

not as much as a 13900k yeah

13900k / ks loves the speed.

[vast geyser]

$300 saved is $300 you can spend on kebabs

[spare sedge]

what are kebabs lol

[vast geyser]

you poor soul

oh my god

im so sorry for you

kebabs are simply the best food in the world

[spare sedge]

lmao oh

ive had kebabs before

[vast geyser]

good

[spare sedge]

im starting to realize after watching so many of these ltt upgrade videos

that my pc is going to be better than most of the staff lmao

[open iris]

Your pc will unironically end up like 6x more expensive than minee

No

Like 12x

[spare sedge]

lmaoo

how

most of the staff is on their 2nd pc in the video too

[open iris]

I have a 12100f and a used 1060

[spare sedge]

dang oldschool

[open iris]

I will be upgrading my gpu to a 5700xt soon though so huge upgrades!!

Only 2 generations behind

[spare sedge]

ill be joining you one day

wait so you have an intel cpu with amd gpu

what if amd starts making ram

[teal pond]

nothing will change with his pc

if they start making ram

but if amd starts making ram choosing to go full amd will be more beneficial for price to performance probably

[spare sedge]

im talking about market cap

[teal pond]

oh idk

[spare sedge]

obviously it wont start off great. but amd is already pulling through on gpus

[teal pond]

Yes, I think once amd fixes the gpu problems for good and releases some better drivers it will be an obvious choice

I think they leaked a 7950xtx

[spare sedge]

very cool.

[vast geyser]

fym some better drivers lol

[spare sedge]

oh btw why do some aios have an rpm range while others dont?

[vast geyser]

+you can never fix gpu problems for good

[teal pond]

If they at least fix the big ones

[spare sedge]

we're talking about the market though.

[vast geyser]

name one

[spare sedge]

best gpu doesnt always mean a better stance in the market. cause people dont usually buy the best gpu.

so its also the company's release history

which just takes time

[vast geyser]

he mentioned amd issues
im curious what

[teal pond]

woopy idk the exact problem I’m just going off of what other people have said

[vast geyser]

maybe bugged?

[teal pond]

also dream I think that is the max rpm.

[spare sedge]

i think at the moment, theres none, just not as powerful as the 4090.

[teal pond]

I think if amd makes more high end gpus they will dominate the market

because of price

[spare sedge]

ik fans can turn off and on, but like. can they just go slower or faster too?

cause pwm is the off and on feature of fans im p sure

[vast geyser]

the xtx is faster than a 4080
2nd fastest gpu

[vast geyser]

yes thats pwm

[spare sedge]

yeah but we dont know if they will reliably sell themself short

[teal pond]

the one that says 2000rpm probably just means that the fan can reach a peak of 2000 and go slower than that but not faster

[spare sedge]

theres a good chance tho

[teal pond]

Exactly

[spare sedge]

ohh so theres not fans that dont adjust at all. all fans must be able to adjust their rpms?

[vast geyser]

not all

[spare sedge]

i mostly agree but it is kind of a toss up with the 4080.

[vast geyser]

molex fans dont
dc fans barely

[spare sedge]

so what does this mean then

there are fans with rpm ranges and then there are flat rpm fans

[teal pond]

ehhh I’ve never heard of a fan like that

[spare sedge]

what do molex fans do then

or dc fans

[vast geyser]

spin as fast as possible

always

[teal pond]

that’s probably it then

[spare sedge]

oh so there are fans with a flat rpm

[vast geyser]

yes

[spare sedge]

is there any benefits of flat rpm over adjustable rpm or no?

[vast geyser]

PWM is like almost everywhere now anyway

[vast geyser]

nope

[spare sedge]

or are adjustable rpm better always

[vast geyser]

just wears out the bearings

[teal pond]

Woopy do higher fan speeds require more power

that might be another thing

[spare sedge]

so adjustable rpms are have the newer pwm technology on it

[vast geyser]

its not that big of an issue

a fan consumes like 1w

[vast geyser]

but yeah

[spare sedge]

so flat rpm is noisier and may consume more power but its fine

[vast geyser]

i guess

[teal pond]

I would prefer adjustable rpm

[vast geyser]

theyre usually crappier cause theyre older but sure

[spare sedge]

ik i want rgb on the cpu cooler im p sure

on the aio if i dont go open loop

[spare sedge]

whats crappier

[teal pond]

The molex fans

[spare sedge]

the flat rpm ones

yeah ik theyre older

[vast geyser]

gl finding molex fans though lol

[open iris]

Molex fans can't be controlled because they are connected directly to the power supply and technically some of them do allow you limited control buy letting you change how much voltage it's letting them get

[spare sedge]

the highest rpms go is 5500 but its air. 2750rpm+ is all air only

highest rpms for aio is 2700

[vast geyser]

where tf did u find a 5500 rpm aircooler

thats industrial at this point

[spare sedge]

nah its consumer grade

pcpp

[spare sedge]

but its only 240mm

they also have a 120mm option at 2700rpm

then theres the 2500rpm aio tier with 360mm 240mm and 120mm options

the highest rpm 420mm is only 2000rpm

[open iris]

You can technically just change the fans on the aio

They are just case fans

[spare sedge]

if 420mm 2000rpm is too big for the case.
a 360mm 2500rpm is available. but if that's also too big.
a 280mm 2300rpm and then,
a 240mm 2700rpm or
a 120mm 2700rpm

there is a 140mm but it seems the most rare

only 10 on the market

[open iris]

Case compatibility is a problem

[spare sedge]

not really since we have the selection from every size

one is bound to fit

[open iris]

No I meant why there's barely any 140 aios

[spare sedge]

ohh

[spare sedge]

none of these are pwm tho

all flat

[vast geyser]

theyre def pwm

[spare sedge]

they are not

they have no range

its only flat

not the 140mm in the picture

here are the highest pwm fans

but im p sure they are all air

[open iris]

Which ones are you on about that don't

[spare sedge]

these ones. im just saying the 2000rpm, 2500rpm, 2300rpm, 2700rpm were all flat rpms with no range

[open iris]

I'm willing to bet it's just pcpp not showing it

[spare sedge]

as a clarification like "yes these are the highest rpm aios" however they are not adjustable.

[open iris]

Actually idek what that range is showing

Cause you can control their speed more than that range

[spare sedge]

and then here are the highest rpm aios that have adjustable speeds

adjustable speeds i have noticed can push higher than some of their flat competition. like the air cooler than can go 6000rpm

and another example here. aios dont usually go above 2700rpm but in the case of having an adjustable one, the fan might be able to push itself by pulling extra power than it should and go an extra +300rpm

it would seem tho, that 3000rpm is the cieling for aio

[open iris]

Again I'm telling you that range has nothing to do if it can be adjusted

[spare sedge]

and 6000rpm is the cieling for air

[spare sedge]

thats not what woopy said

i doubt its cause pcpp forgot to write it down

most aios also dont have adjustable fans

i would doubt everything i am doing, but its all so consistent so i doubt i am wrong

[open iris]

they literally all do

[spare sedge]

most aios have flat rpm fans

[open iris]

No range

Website for it itself

Aio fans aren't special they are just case fans like i said

Well they are static pressure but case fans can be

The only fans in a case which you can't control the speed would be ones with a molex connector

[spare sedge]

the highest adjustable aio fan is 420mm with 2000rpm max

[open iris]

are you just ignoring what I'm saying

[spare sedge]

thats a flat one

[spare sedge]

thats for this one

[open iris]

Literally just look at the product page https://www.corsair.com/us/en/p/cpu-coolers/cw-9060046-ww/icue-h100i-elite-capellix-liquid-cpu-cooler-cw-9060046-ww

[spare sedge]

thats not this one

[open iris]

It is 🤔

[spare sedge]

corsair doesnt list the range

[brave brook]

You can replace the fans anyway

[spare sedge]

just found out dc is the opposite of pwm

[open iris]

Idk what the range is meant to show

But it's not showing how mucy you can adjust them

[spare sedge]

the lower level

[open iris]

You can set all of them to 0

[spare sedge]

thats just turning them off

[open iris]

So the range really should be 0- whatever if that's what they were trying to show

Anywhere to 0 i should say

You don't just set fans to like set numbers

[spare sedge]

you probably just can't do inbetween 0 and the min

[open iris]

You 100% can

[spare sedge]

im guessing the fan wont even move if set to something like that

100 rpm is movement

but maybe the fan just doesnt start until after

[brave brook]

There is a minimum, usually around 200rpm

Well, for higher end fans

[spare sedge]

im guessing its because of something to do with power draw and how that particular fan pulls power. its not really a big deal

[open iris]

Anyway

[spare sedge]

all of the minimums are usually 100 to 500 rpm

[open iris]

My point is that range isn't showing if you can control it or not

[spare sedge]

but look in this example. these are kind of like semi pwm where the min is relatively high at 2300rpm

meaning this pwm fan is more like a dc fan

[brave brook]

You can control all 3 pin and 4 pin fans

[spare sedge]

not all fans have pwm

[brave brook]

Ok?

[spare sedge]

but you can probably turn a fan to 0rpm yeah

[brave brook]

3 pin fans are still controllable

[spare sedge]

just say pwm or dc

[brave brook]

Ask me how I know. I have them

[spare sedge]

unless you are ready to tell me which one is which

[open iris]

The only fans you can't control are ones powered by molex I've said this

[spare sedge]

im guessing 4 pin fans are pwm

and 3 pin is dc

[brave brook]

Yes, 3 pin is dc controlled

[open iris]

unless like I also said there's like a proprietary power controller

[spare sedge]

its not controllable its just turning off the power lmao

[brave brook]

For 3 pin? Yes it is

[spare sedge]

not the same as lowering the speed to 500rpm

[brave brook]

I have them and they’re controllable

Not as controllable as 4 pin, but still controllable. But you should get 4 pin fans anyway

[spare sedge]

exactly dont try to confuse me when im right

all im saying is that the rpm range on pcpp is correct

and that i shouldnt choose a flat rpm fan

[brave brook]

It sounds like you’re saying 3 pin fans are either on or off

[spare sedge]

is that not what it is?? are they able to adjust their rpm??

[brave brook]

Yes

[spare sedge]

how??

[brave brook]

I said that at least twice

[spare sedge]

that is literally in spite of it being dc enitrely

no weve been talking about the exact opposite

[brave brook]

All pc fans use direct current

Using the 3rd pin (the tach pin that senses the speed)

[spare sedge]

https://resources.pcb.cadence.com/blog/2020-pwm-vs-dc-fans-fan-speed-control-strategies-for-cpu-cooling-and-case-ventilation

[spare sedge]

its the 3rd pin on the 4 pin connector. just explain it better geez

[brave brook]

What?

[spare sedge]

why say the 3rd pin when there are 3 pin and 4 pin headers

its just confusing cause someone might confuse 3rd pin for the 3 pin header

[brave brook]

I don’t know if there are any 3 pin fan headers anymore

[spare sedge]

what??

[brave brook]

I don’t know how you’d do that but ok

[brave brook]

All new motherboards have 4 pin headers

[spare sedge]

also nobody calls pwm fans dc fans because yeah they use dc but it doesnt matter

[brave brook]

3 pin and 4 pin fans both work with 4 pin headers too

[brave brook]

Yeah i know

I never said anyone did

[spare sedge]

also its the 4th pin apparently not the 3rd pin

[brave brook]

For 4 pin fan control yes

I was talking about 3 pin fans though

[spare sedge]

the 3rd pin is the signal pin

for dc

3 pin fans speeds are just controlled by more or less voltage and usually have less control. 4 pin honestly idk how pwm works but you have more control and it's better that's one for Google

Well, it’s the signal pin for both, but it is the pin that allows for fan change, because it senses the speed of the fan

4 pin pwm fans use a small chip on the motor hub to control the speed more finely

then how was the aio you posted pwm with a flat rpm speed

[open iris]

Cause it isn't actually flat

[spare sedge]

it says its flat on pcpp and on their website

It doesn't say that on their site though

[spare sedge]

it does

[open iris]

Where??

[spare sedge]

the exact same specs as pcpp

[open iris]

It literally says it's pwm there

[spare sedge]

yeah but look at the rpm

[open iris]

I know I've seen saying that's not a representation of if it's controllable

[spare sedge]

i already know you can control dc but turning it off and on really quickly

i already know the methods are different

i already know pwm is better

what does the rpm range mean on pcpp?
