I recently bought a slightly used PC. Had to install the GPU myself, but no issues there. I was setting up Google and steam and all that and about 15-20 minutes in the fan goes crazy and the PC just shuts off. I start the PC again and it tells me that the CPU has apparently overheated. I let it rest for about an hour and turned it on again. This time I download some stuff that'll let me monitor CPU usage and temp, and I even scanned for malware. Suddenly about 10 minutes into my monitoring, the temperature starts absolutely rocketing. I checked the usage and it was at 2%, yet the temp had gone up to 90°C, which is when I shut it off again. What could be causing this?
#CPU overheating with very low usage

send specs
and also i have a feeling you either didnt apply thermal paste or you forgot to take the plastic sticker off of the cpu cooler
hello?
the PC is used. I just mounted the gpu
so you bought a used pc from soneone?
slightly used, yes. I think you should read this
Because the behavior is very weird
well maybe the person who built the pc is an idiot and forgot to take the sticker off of the cpu cooler, assumed it was broken, and pawned it off to someone else
It doesn't just start heating up slowly but surely after I boot it up. It'll have random spikes of cpu temp rocketing
just remove the cpu cooler and check for yourself, thats the most likely issue as nothing else makes sense really
i would say the motherboard could be overvolting the cpu but i doubt it
under the cooler, between the cpu and the pump
its on the cooler where it makes direct contact with the cpu
What does that mean?
just unscrew it
the thing that says nzxt
lemme give it a go
means its sending too much voltage at once but it doesn tmake since if it were overvolted then the pc would just cut off immediately
there are plenty of tutorials on that specific cooler if necessary
and probably would be fried already
nah it definitely still works
how much did u pay for it?
a 5600 and 3070 pc is worth around $800
Not in Norway lol
the person who had the build before you didnt make great choices when it come the components they chose
yeah but if it was assumed to be broken it would prob be cheaper no?
like why is the motherboard more than the cpu lmao
Paid 12k nok. Woulda costed 20k if I bought each part individually
they focuesed way too heavily on aesthetic and couldve gotten a similar looking build with specs that would yield 30-40% more performance
i really doubt that and i ll try to prove you wrong rn
he told me he's selling it because he barely used it
so i should pick a motherboard cheaper then the cpu i chose?
go for it
for the meantime you should remove the cooler and check if he removed the cpu
doesnt make much sense
*sticker
but I already checked each part at komplett.no
on it
pcpp is a better site for this really
it does tho
not if you are trying to future proof, which wouldn't make much sense with am4 since its discontinued
only time you get a motherboard more expensive than your cpu is when youre already buying the highest end cpu and trying to achieve world record overclocks
yeah but a 10 euro difference?
if it were a 300 mb then yeah, i would agree
yea but with how much they overspent on the mobo they couldve gone am5
well with how much they overspent overall
but since the budget isnt that fat they coudlve stayed am4 and gotten lower end mobo
maybe it hadn't released when they built it?
who knows
yeah
could've gotten the non x version and a 6900xt
thats why i think this is an "older" build
6900xt needs an 850w psu at least tho
also the corsair vengence ram is ass
???
only at 1080p it would which why would you spend more than $350 on a gpu when doing 1080p
since when
update
ddr4 vengence ram has issues running at xmp
advertised speeds
quality control issue
and also theres better cheaper alternatives
ive never seen anyone have any issues with it
now I assume I just unscrew?
remove the 4 screws around the cpu block
on it
ive heard of so many issues you can check forums too
I think I've gotta unplug this?
yeah
how much ddi the build cost in KR
alright unscrewed
from the reseller?
yea
12000
around 1000 dollars right?
yeah, if you have it un screwed
uhhh
dont pull it hard if at first it doesnt ggo
https://no.pcpartpicker.com/list/3NmBQ6 guess you were right, not bad value aside from the 3070 (8gb of vram is meh nowdays)
Part List - AMD Ryzen 5 5600, Radeon RX 6800 XT, Deepcool CG560 ATX Mid Tower
do I disconnect this wire too?
not at all
show us the side that the cooler was on the cpu
not needed rn, just send a pic of the thermal paste on the cooler
then yeah disconnect it
unplug it
i guess there isnt a sticker on it?
welp
maybe a deffective aio/cpu?
if the temps are spiking then id probably blame the cpu
do the fans do anything @ornate bluff
he did say they would spin like crazy
yeah, prob the cpu then
guess one more thing he could try
well for starters just plug and screw everything back in
oh yeah for sure
they're definitely going off
then the aio seems to be good
its probably the cpu then, but lets wait for captaine
oh man
then try booting the pc again and get into bios or use ryzen master to check the voltages on teh cpu
do you have thermal paste?
no unfortunately not
I believe it was normal when I checked
I'll screw everything back on hold on
i recommend re pasting it.
https://www.reddit.com/r/buildapc/comments/l7aeef/cpu_randomly_overheating/ im reading this rn, same cpu and mobo
also an aio
also the aio may be mouinted poorly, but ill ask the main chat
yeah it is
.
fuck idk what that is
oki
its the cpu cooler where the two fans are
besides I don't think that's the main issue anyway lmao
its just a bit lower than what it ideally should be
but no need to mess with it yet
the more I tinker with this thing the more likely it is I'm gonna break it istg
gotcha
i do think its the cpu, i dont think the temp would spike up to shutdown even with that config on the aio
nah pc parts can take a beating, linus drops every gpu and cpu on the floor at least once when he builds a new pc
to be fair if you drop an amd cpu (minus the am5 ones) then you could be in trouble
and yea its probably a bad cpu
I've definitely seen that lmfao
most likely at least, though its not like you can get another one to test unless you wanna spend 20-30 bucks on a very old zen cpu
man fuck
to test it out
am I gonna have to buy a new CPU?
can you refund the build
unless the current one has warranty
nah too late for that unfortunately
damn
maybe it has warrantly liek void said
they have a 3 year warranty
oh youre within warranty
the cpu?
they released nov 2020
mhm
so you got warranty till this november
the guy sent me all the papers and shit that he had
lemme check if anything is CPU related
I don't need to install the panels to test it, right?
if you have proof of purchase then you can prob send it to amd
or even the store that sold it to the guy
nah
i don't remember what it was
the config of the aio i think
dw about the aio its most likely fine
unelss youre hearing a loud ass noise from the pump
nope, it was this
I'm hearing a loud ass fan noise when the cpu starts overheating
yeah, 1 problem at a time
well fan noise is fine
thats expected
I'd argue it's good lol
definitely
what do the papers say?
actually there is another thing you can try
since its corsair ram
try disabling xmp
you could still email amd, not sure if they require proof of purchase
and see how the temps work
what's that?
extreme memory profile
basically ram overclock
i can see its enabled rn
sure I'll do so, but I imagine they'd like to know when I bought the cpu lol
oh how do I disable it?
oh yeah, forgot about that lol
bios again?
if you disable it it will run at stock 2666mhz or sum around there
yuh but how
Hello,
Here's another quick tutorial video for enabling your DDR4 memory sticks in a ASUS bios. Most of this stuff is for those using an ASUS bios but the principals will apply for other motherboards as well.
I have a kit of GSkillz 32 gig (2x16) 3600MHz DDR4 memory. *NOTE: The ''FCLK' value in your bios should reflect a value of 1/2 th...
thats for intel actually
standby 1 sec
boot up pc, spam the delete key to go into bios
on the left side of the screen you should see memory profiles or sum like that
it will say xmp profile 1 or something like that
3600mhz
go to advanced and take a pic
i guess another thing you can try
but I do think we're on a timer here lol
hold your hand on the tubes
and see if you can feel it flowing or pumping
yea thats it
I honestly have no idea lmao
oki done
does it say 2666mhz now
booting?
or 2400, anywehre around there
I wish I had a friend who knew PCs for this shit
@hollow walrus I can switch it manually
which do I pick?
2666mhz should do
so why can't it handle 3600?
oh it still hasn't changed, but maybe I just need to update it
cuz its corsair vengence ram
yea just exit and save all settings
when you do that it will restart the pc and take you into a normal bootup
how
go to the exit section
oh lmao
yes, it's in the ai tweaker section of the bios
dw he got it
save changes and reset?
yea
you'd probably find it would do xmp but with the freq reduced to 3200mhz on the kit
I just wanna mod Skyrim bro 😭
i do modded skyrim vr, annoyingly enough i get issues the farther i get into the game
i got the exact ram and the non x version of the cpu and it works just fine
did you enable xmp tho
also just cuz you got the exact ram doesnt mean everything
not all 5600xs are made equally
same with teh ram
why the fuck is there something called goodgame empire on my desktop
every ram has its issues, sure one has more than the other but every ram brand has had issues
maybe the old dudes bloatware
an r5 5600 can do 3600mhz ram, but you'd have to be careful with corsair, as you go by the revision number to tell if it's a decent kit or not
with windows or an actual format
uhhh idk the difference
idk, it is a virus it seems
did you use windows to erase the stuff or did you use a usb drive to erase everything
windows
how do I get rid of it?
wait, rauko is typing
it's not in my files or anything
windows has a reset feature built in, or did you do a clean re-install via widows installer usb drive
try formatting the pc with a usb
like rauko said above
anyways i gotta go, good luck kurat
didn't use a usb drive
used the built in one
thanks man, have a good one
well that's not a wipe then tbh
I really appreciate the help
man fuck
it is wise to always do a clean install/re-install via windows installer usb drive
and it's really easy to set up a windows installer drive, with the use of windows media creation tool
you just need an 8-16gb usb drive
yuh I already got it installed
I'm afraid I've got malware or something
and that's the reason for the weird spikes and shut off
shouldn't be causing it at bios level tbh
hmmm
usually that's a poor mounting/dead pump
nzxt doesn't have a great record in the long run for aio's
b-but theyre severely overpriced!
again
utilization also spikes for some reason
use hwinfo for measuring system temps, not coretemp
did that guy plant a crypto mining thing in my gpu or something
sure, what's the difference?
more readouts/higher accuracy
as long as it's free
it is
it definitely is
alright got it
sensors panel
oh god so much info
if the temps spike out of nowhere shouldnt it be a software issue?
can't find it
considering software issue is what would cuase stutters in games for me
it's an option on hwinfo
click the X on the smaller summary panel
sensors
right on the bottom of sensors there is 2 buttons with arrows
yep
one with the arrows pointing outwards, click on that
should make it look similar to this
right any program loading up will register as a small spike in temperature change normally
which would mean a background task loading up
I barely managed to download Spotify and discord before it just randomly overheated and turned off
but for you to thermally shut down because of a spike would mean a possible deeper issue
yeah I imagine it's something related to the hardware
or maybe it's both
maybe I've got malware + hardware issue
a quick way to test if the pump is actually working is to feel the pipes, you should feel a vibration of the coolant flowing through it
it's actually been running around 30 for 20 minutes now, which is the longest time so far
yeah so captain said the same thing
if you don't feel any vibration, then we're looking at a possible dead pump
I have no idea if I'm feeling anything or if my brain is making me feel things that aren't there
is it a really obvious vibration
or subtle
should feel like when you run you hand under a tap
yup
you never held your hand under to check the water temp roughly as it flows out?
I feel a slight vibration, but certainly not that
idk I just kinda put my hands on there
the tubes feel slightly warm
a slight vibration should be the coolant flowing
probably fine then
something loaded up again in the background
what the fuck
WHATS LOADING UP
I hate this lmao
is there a way to check or do you suggest just completely wiping with a flash drive like you mentioned earlier?
windows has a fair few background tasks that keeps it running, one of them being windows defender antivirus
ah
a complete wipe and start from there, though if you got a spare second usb drive, i would use that to put all the drivers on from the mobo and gpu manufacturer's website
oh btw off topic, but have you ever had steam just not letting you log in? I've literally reset my passwords three times and it still says something might be wrong
also update the bios
I've got like 100+ gb on my current USB drive
I have no idea what a mobo is
or what drivers are
nor do I know how to update the bios
Jesus Christ I feel so outta my depth
mobo= motherboard
oh gotcha
alright so it's been running for 30m without overheating
so I think I'll go to bed for now
I'll leave an update tomorrow and if it overheats again, I'll wipe
Thank you all for the help!
small update: is 60% utilization normal for just downloading wallpaper engine?
Sounds like a dodgy AIO pump to me, just because it's buzzing doesn't mean the pump is pushing any coolant. IMHO air coolers are cheaper and better in that there's so much less to go wrong
The rise in CPU usage in your screenshots looks to match with downloading updates as your network usage spikes at the same time.
also can be spikes caused by windows defender running a scan, let alone other background tasks running, still though he shouldn't be spiking to 90c and it thermally shutting down at that point tbh
@grim fulcrum do you think maybe the cable that connects the pump to the heat sink might be loose?
it's possible, loose cable can cause a not working device, or have it intermitantly working
I can't really find where the cable even is tho lmao
well the usb cable should go off to one of the usb 2.0 headers, and there should be a cable that splits into 2, one for power and one to go to a fan/pump header
I saw that the fans are running, but have or been checked that the pump in the AIO actually runs?
can I get a tl:dr of the thread so far?
simply put the pc has shut down the moment it spikes to 90c
also the ram isn't holding it's speed
Troubleshooting steps taken so far?
Also here's the specs in user-friendly format.
Motherboard: Asus ROG STRIX B550-F GAMING ATX AM4
Memory: Corsair Vengeance LPX 32 GB CL18

PSU: Corsair RM750 80+ Gold Modular ATX
@ornate bluff
oh hi I'm here
I'm trying to catch up but the thread is 400 messages long and I'm not about that.
well afaik, mounting being checked, a feel test of the tubes to feel if there is a flow rate going on inside the tubes
I can see the original.
I don't need a refresh.
More like, looking for a current affairs message.
i know the reason as to why the ram isn't holding it's speed
Gotcha
it can be summed up as "it's corsair lpx's"
but it's more the ic's used for the specific kit he's using
Yeah so I haven't turned it in since last night. I'm getting a new power cable in about 30 minutes to an hour
Kinda nutty that the 3070 new is still $700+ and still only a 8gb card
I have no idea what this means
Makes you wonder if there's a collective effort going on to refuse to sell ram to Nvidia on the cheap :P
Since they're really, really skimping on it.
I messaged the guy who sent me it and he believes there might be something wrong with the cooler, so he's sending me another one
he also sent me this
NZXT Support Center
If your Kraken X53, X63, or X73 pump is not running and your CPU is overheating, first please verify if the cooler is visible in our CAM software. If the product is not visible in CAM, this is a se...
told me to download the nzxt software and I apparently should be able to test the pump
I haven't opened the back panel to check the cables yet
your ram
do you think the issue is the ram?
not for the overheating
what for?
for the not holding it's speed stably for xmp
Cheers, someone's already quoting my text only specs :P I figured those would come handy.
I didn't have any issues with xmp on
thank you for that btw!
the amount of tech help messages from when this used to be a chat and not threads that 9/10 was due to it being corsair ram
Now if we could somehow educate OPs to provide those, that'd be neat.
you wrote 3080 instead of 3070 btw
that's not what you said earlier
everything else seems correct
I was wondering about that, lemme double check.
No captain from yesterday told me to turn it off and thought that might be why there's overheating
So I did, but it still overheated
however it lasted longer before overheating than when xmp was on
about 10-15 minutes longer
Fixed to 3070, thanks.
god I wish I understood this shit better so I could communicate things more clearly. I'm very sorry about that
then the ram is causing you some instabilities as the xmp profile is not working as stable as it should be for the ram
What's the primary problem?
and that is a separate issue along side the overheating
the overheating tbh
Random overheating after 20-30 minutes of use
Literally spikes from 40c to 90c for seemingly no reason
90c spike that thermally shuts down
Okay so.. that's not something that has to do with thermal paste, or coolers or something. That's a software/hardware issue.
Something just smashes your cpu with a load it can't handle.
huh
yeah so I'm gonna wipe the PC completely when I get my power cable
reinstall windows with a USB drive
see if that fixes anything
If it goes out of the blue from idle 40 temps to 90 and you can't figure out why.. that's a bit scary.
if it doesn't, it's probably a hardware issue I imagine
it is indeed
Clean install sounds like a good way to start figuring this out.
Alright, you can ping me too, I don't mind those.
Will do!
same here yeah
oh, well then I might respond pretty quick :P
I live in Norway, so CEST for me
Turku here, south coast of Finland.
oh shit interesting
Anyhoo, good luck with the reinstall.
Thanks, I'll let ya'll know
alright I got the power cable
@steady kernel cloud reinstall or local reinstall?
@grim fulcrum
Oh
Well then you're gonna have to walk me through it if you don't mind
I guess I'll just turn the PC off again?
thought you said you setup windows install on a usb drive>?
no no opposite
you suggested doing with USB drive
But I did it through windows itself
then why you said you had that already on a usb drive when i asked last night?
though I did download windows on a usb drive
because I didn't know the difference between the two
I ended up not needing the USB drive for the method I used
But now I know they're two different things
So basically I have a USB drive with windows. How do I go about this now?
yeah
again I didn't know the difference between the two methods
I assumed that the only way to reinstall windows was with a USB drive
did you run windows media creation tool to turn it into a windows installer drive?
No
because if that hasn't been done then you don't have a windows installer drive
I just installed windows media creation tool on the USB drive and installed a new PC setup or whatever it was called in the drive
actually yes that's probably what I did
lets see a pic of it
when I installed windows media creation tool on the USB drive, it asked if I wanted to create a new windows installer or whatever for a new pc
which is what I did
one sec
when you do that, it will wipe a usb drive into turning it into a windows installer drive
btw can I just shut off the computer in this state?
which is part of why i said about needing an 8-16gb drive with it, and a second drive with drivers for gpu and mobo on
I just have one unfortunately
also weirdly enough the CPU of the PC is completely fine in this state. The fan isn't having those sound spikes, which tells me that there aren't any temp spikes happening
right, when you restart the pc, you need to go into bios, go to the exit page and click on load from efi
okay so it's fine to shut it off in this state?
It's currently in the reset pc screen
yes
the button doesn't work, so I'll have to shut it off from the backside
as you'll need to run the installer from the usb drive itself
yeah plug it in right?
yeah, should be in before you start it up
nope
Temp is at 75c for some reason
84
I gotta shut it off
fuck
@grim fulcrum how do I disable the secure boot option?
enable CSM on the boot tab
and restart it back into bios
I literally can't check it's at 86c again
Fan menu
But after doing that just check and speed it up if it's slow or not running.
sure
It should be in the fan menu
where is the fan menu tho?
Qfan control menu maybe?
the fans are definitely working btw. It's the pump I'm worried about
oh gotcha I'll check
hmm, check the secure boot option and see if it's set to windows, or other OS's
You made sure that the cable for the pump is connected to pump on the mobo right?
and yes Qfan is the main fan control though you can access the fans via monitor tab
On both sides if so then check bios.
I don't know about that specific mobo and AIO but maybe pump setting on PWM/DC is set to the wrong thing PWM is 4 pins used whole DC is 3. If it's wrong I am not sure what happens.
no I don't think so
Jesus Christ temp went to 100c
I can't even turn the thing on
fucking hell
I'm not sure how to check this
nvm I checked
it's definitely connected
that's the cable
the one on the right side
it's bent however on the backside
is that even safe?
looks like it might break like that
uhhhh idk what I just did, but
i mean I messed around with some cables
and now the cpu temp is somehow back to 30c
and the fans are quiet
Hard to know how that looks on the inside.
That is not the cable/wires itself bur rather a thing on the outside of it.
oh shit the tubes are vibrating more than they did earlier
I can actually feel the liquid running through
yeah ik
You didnt before?
Pump should vibrate little bit yes.
maybe it was a cable issue, not sure, or yeah, maybe cable not pushed in.
yuh
idk we'll see. I'll let it run for a bit and leave an update here if something happens again
i also clicked optimize fans in the bios btw
right so I don't really know what I did
but it's been running for about an hour now
and the temp has been consistent
no random spikes
no shut down
a good 35c all the way, besides when I downloaded a game when it rose to around 45c
Which I'd assume is normal
I'll see if gaming on it will do anything
Nice
nice lol
Thank you guys for the help btw
np
Made me feel like I wasn't alone in figuring this out
what fixed the problem anyhwa
I was messing around with the cables making sure everything was properly plugged
Then I kinda just started the computer again and it worked
I also optimized the cooler in the bios
So the problem was either a loose cable or the cooler needed to be optimized
or both
