heating problem

[true cliff]

model: lenovo legion 5 pro , rtx3070ti
issue: over heating but it is weird
i did not install new drivers
i did clean and ptm and all things but my gpu reach 85 and when i lift laptop all way up it is still 85 degree, but when i put laptop on side like 90 degree in air , i get insta temp drop from 85 to 77 with in 1 to 2 minutes so i do not understand what is going on

[sonic pelican]

The air passages is restricted likely

iirc it's still behaving same as we discussed on your other post .

Was the wattage stays same when temp drop to 77c?

[true cliff]

yes 150 watt

but i tried to lift laptop while flat , it was still heating

i rotate it to 90 degree

magic , heatsink works normally

[sonic pelican]

iirc i told you to not use the cooling pad you were using? Are you using that still?

[true cliff]

no im still lifting up

[sonic pelican]

Not with the cooler underneath

[true cliff]

but i just do not understand why i get no result while lifting it up flat and i get insane result on 90 degree

[true cliff]

yh nothing down there

wait

[sonic pelican]

I would like to see 90° lift you are doing and the normal lift

[true cliff]

90 degree like

i lift laptop

[sonic pelican]

Show picture

[true cliff]

wait i will take picture , kinda hard to do

litterly tilting laptop like this

made my gpu in AC 74 degree and with no AC made it 76

but from lift side

if i try right side , it will give opposite result make my gpu hit 86 in 1 minute xd

[sonic pelican]

This is how you should lift the laptop

[sonic pelican]

Open it up and clean fans and exhaust vents

[true cliff]

i did month ago

with brush all vents were clean

[sonic pelican]

But the issue persist

[true cliff]

yh

i mean

[sonic pelican]

#chat message
This is how you clean properly

[true cliff]

i remember when i screw heatsink

there was one screw

that was doing friction

like i felt screw doing friction to something down there

[sonic pelican]

Heatsink probably not seated properly

[true cliff]

yh right

i felt it , but i tried lift it up and orient it right

and same screw does his friction thing

[sonic pelican]

These are only few things you can do

1. Clean fans and exhaust vents with compressed air
2. Repaste again and screw the heatsink properly

[true cliff]

they do not sell compressed air in this country

can i use lubricant oil

[sonic pelican]

No

Buy electric air duster that are advertised for electronics

[true cliff]

but it is probably the mounting issue right

i may try to like

[sonic pelican]

Could be

[true cliff]

unscrew all screws

and screw that friction thing first

and see if heatsink goes down

if it goes down , it means it works ?

[sonic pelican]

You'll have to repaste then

[true cliff]

would have to wait 20 days untill new ptm arrive @w@

but atleast it should give decent result with old ptm

not 85

[sonic pelican]

Not sure what issues there is maybe not properly aligned or maybe the screw ring is causing problem

[sonic pelican]

Who knows

[true cliff]

i mean i did take off heatsink alot of times

there is like rubber things under fan screws

it got stripped , so fan screws do not work anymore

[sonic pelican]

And you never repaste again?

[true cliff]

i repast ptm twice

last ptm was last month, and i did not take off heatsink

[sonic pelican]

When you lift the heatsink you repaste no matter what .

[true cliff]

yh that is why i wanna fix that weird thing with out ptm

it is the weirdest shit ever

[sonic pelican]

Fan screws ?
On the heatsink?

[true cliff]

that weird lift fixed overheating

[true cliff]

yes those small ones

i screw them in

and they are not intact like they are usless

lose screw

[sonic pelican]

Then it will cause problem again

You'll need some extracter to remove those and install new ones

Until and unless they are not screwed properly, heatsink won't work at its full potential

[true cliff]

they can get removed easily

i tried to duct tap them

but i think there is like small rubber ring

that hold the small screws in place

and those ring are teared

[sonic pelican]

Yes could be, there are rubber type thingy in them

That's why you need new ones

[true cliff]

where can i get one

[true cliff]

those are heatisnk ones o: ?

i thought they are not removable

those are the small screws i talked about

[sonic pelican]

[sonic pelican]

You can disassemble them

[sonic pelican]

Serch on Google maybe

Or if you still have warranty ask for heatsink replacement

[true cliff]

how do i dissasemble them

do i push them

from down

[sonic pelican]

That's probably are not related with your issue , you should care about heatsink ones , should be 6 of them .

__Disassembly guides__

To get started you will need -

• A proper screwdriver kit with pry tools and suction cup Example
  or
• PH00 or PH0 screwdriver
• Pl...

Result 1 of 1

[sonic pelican]

Watch thr guide here , see if they showed for your model

[true cliff]

oh

for heatsink screws all work fine except that frictional screw

is sussy

[sonic pelican]

You'll only know by doing these to eliminate these possibilities

[true cliff]

will do , i will do it tmr and tell you what happened , thanks

[true cliff]

ello @sonic pelican

[sonic pelican]

Hii , doesn't look good to me .

[true cliff]

hi

there is like

that screw

that i think it does not go all way down

[sonic pelican]

And it's gpu on that side aswel

[true cliff]

i unscrew then it lift heatsink

and screw it again

[sonic pelican]

Yeah that could be the problem

[true cliff]

yh

there is also other screw

i told you abouty

waitt

turn on volume

it is like asmr

[true cliff]

that screw i feel like it is not screwed all way in , and i tried to like move screw or something but it is how far i can go with it

[sonic pelican]

Screw ring is stripped

[true cliff]

those stuff can get stripped

jesus

[sonic pelican]

Also your fans are not clean

[true cliff]

spring got stripped

oh i used lubricant oil on it yesterday

my home is dusty

it is kinda the normlal here

[sonic pelican]

Yes , you mentioned you have disassemble many times , something had gone wrong during process

[true cliff]

i would have to clean it everyday

[true cliff]

i though stripped is like

from outside

not inside

[true cliff]

but that screw surely not screwed all way in

[sonic pelican]

No the screw on the ring can also get stripped or whatever they call it , they won't work properly as they used to

[true cliff]

then my problem is heatsink mounting

[sonic pelican]

Yes

[true cliff]

so i should order

replacment screws

i opened link you sent me yesterday

could not find a way where they remove screws from heatsink

[sonic pelican]

This?

[true cliff]

yes

i might just order screws from ali express

but idk how to take that spring screw out

[sonic pelican]

You'll have to research yourself for those thing, lenovo won't tell you how to remove

[true cliff]

you removed those by urself ?

[sonic pelican]

That's the kuri's picture and he removed himself i think

[sonic pelican]

@cinder hamlet
Tldr: the person is asking how to remove captive screws from heatsink

[true cliff]

chat gpt says just keep unscrewing xd

yh also that guy got same model

[sonic pelican]

We don't use chatGPT DUDE

[true cliff]

zzzzzzzzzzzzzz

i kinda wanna try

removing them and put them again maybe spring jjust work by is own

wish

[cinder hamlet]

@sonic pelican @true cliff to remove those screws, you'll have to remove the heatsink, which means a repaste is required

[sonic pelican]

That's obvious kuri

[true cliff]

if i remove that screw, can i put them back again ?

[cinder hamlet]

carefully remove the plastic washer

[true cliff]

where can i find it

on board ?

inside screw holes

[cinder hamlet]

under the heatsink right where the screws are

[true cliff]

I think

I see something

[true cliff]

@cinder hamlet

[true cliff]

Bro just left me drowning 😭

[fair brook]

same issue but CPU tho. and it makes me really mad.

[true cliff]

You can not scew all way ?

[fair brook]

no, overheating in general

[true cliff]

Can you try 90 degree trick

Run heavy game and hold your laptop in 90 degree

[true cliff]

.

[fair brook]

I’ve got cpu heating. GPU it’s around 85-87 while 100% loaded

Meanwhile cpu 50% goes to 101-102 degrees

[fair brook]

I have no idea how to do it

[true cliff]

You think 85 to 87 is good 🙂 ?

[true cliff]

It's easy

Just run the game

And hold your laptop but not from vent parts

[fair brook]

U mean lifting back to 90 cone ?

[true cliff]

Yh

[fair brook]

I have about 50-60 cone on my pad. 90 are unreachable for me I guess
Anyway I guess problem somewhere inside
May be thermalpads or smth, I really don’t know
Repasted it about 1 week ago

[true cliff]

With ptm?

[true cliff]

I don't mean 90 90

[fair brook]

Xd

[true cliff]

You see how this guy holding laptop

Hold it like him while running game

From left side

[fair brook]

And what should I see there

[true cliff]

Do one on right and one on left

[fair brook]

Sry for my eng knowledge

[true cliff]

For me it decreased my temp by 5 degree

[fair brook]

Hm

[true cliff]

I wanna see if it is design flaw or is it only me problem

[fair brook]

But in this position side airducts gonna be blocked, no?

Nvm I’ll try

[true cliff]

No if you keep carrying it

Don't block vents just do all of that while laptop in air

[fair brook]

Nah, temps went up
I think this position changes nothing for me

[true cliff]

Try opposite side

Like the other side

[fair brook]

Already

[true cliff]

For me one side decrease temp , other side increased temp

[true cliff]

But if your temp still go up even with AC you are cooked bro

[fair brook]

May be idk

[true cliff]

You tried other side and no effect?

[fair brook]

Yes. Looks like nothing changed

It was 101 and remains 101

After all manipulations

On full max fans

[true cliff]

Yh then my heatsink mount is so ass

[true cliff]

4800 ?

[fair brook]

4500

[fair brook]

Which one you have ? I though we have +- same constructions

[true cliff]

Set it to 4800, paste ptm , don't fuck mounting like i did

Mine looks permanent idk a way to fix it

[true cliff]

Your model 2021

Mine 2022

They are close but a little different

[fair brook]

Bro did u met any freezing or shattering ? I though 85 degre its fine for these gpus on full load, no?

@true cliff seems like 85 on your gpu while gaming it’s ok

[true cliff]

Noo

Mine is rtx 3070 ti

When i

Do the trick i told you about

With AC on, it makes my gpu 73 degree🙂

On full load for like 10 minutes

When i do trick with AC off, 78 degree to 77

[fair brook]

Meh

[true cliff]

Without the trick and AC off gpu hit 82 to 83

85

On hot day

[true cliff]

Bruh those temps are god like if AC on and trick

[fair brook]

Idk, i had 2 laptops in my life
And I think the best way is to build desktop pc
I’m really done with these temp issues

[true cliff]

Yh lol if you got option for desktop then laptops are trash , laptops are for certain ppl

Like i live 10 hours away from home and i move alot and uni , then gaming laptop for me

If you got gaming laptop for no reason then it's dumb decision

[fair brook]

I’ve got laptop just cause of moving from 1 rent apartment to another. And like now, I can move to another country for 1-2 months. But for now I guess better decision to build mini itx pc or smt

[true cliff]

Yikes how about moniter

Those stuff gonna cost you more

[fair brook]

That’s the only problem man

That why I’ve got laptop

[true cliff]

Portable monitor exist and they are expensive

[fair brook]

I’ve checked
Not really expensive
Like 180-200 $

[true cliff]

damn i guess because i live in third world country

[sonic pelican]

Guys stay to the topic , if you want casual talk #off-topic

[true cliff]

But what do i do about it

I look at screw under heatsink it looks exactly like others

[sonic pelican]

Where?

[true cliff]

This one

I looked online but it's different model , the exact same screw on top left

I think those stuff around gpu prevent it from getting fully screwed

Yh it's actually the normal xD

[sonic pelican]

Look at your picture, it definitely need more turn.
