Acer 5750g overheating & throttling PERMANENT FIX!

Hi Guys
First of all, sorry for my bad english and for bad quality of pictures (taken with my htc desire z).

As far as I know, not only me but many users of this notebook have a frustrating overheating problem with causes CPU/GPU throttling and sometimes emergency shutdown..
I have tried:
- Replace stock thermal paste on CPU and on GPU! (yes, my 5750g-2452G75Mnkk has a thermal paste instead of thermal pad)
- Clean dust from cooling fan
- Use cooling pad
- Flash different bioses (even undervolted gpu)
- Use ACfan Control utility

and none of these above worked ..

So few days ago I came with a brilliant idea and in this post I will show you what I've done So lets start:


Warning!
All of those things you do at your own risk, don't blame me if you brick your laptop.
And last one info - yes.. you will lose your warranty.

Spoiler

What we need:
- Screwdriver
- Something to cut plastic and aluminium, I used small sharp kitchen knife and tape cutter
- Sand paper
- Aluminium mesh (smallest one)
- Glue or something else to link aluminium mesh with plastic
- Thermal paste (My suggest is GELID GC-EXTREME)



1. First what we need to do is disassembly notebook.
How to do this?


2.
Then cut two holes like on this pictures

First hole (GPU)
View attachment 103476
View attachment 103477

Second hole (CPU)
View attachment 103469
View attachment 103470

And it should looks like this when we put Motherboard on its place:
View attachment 103471
View attachment 103472

3. Next step is to wipe the edges and cover these holes with aluminium mesh
(Sorry, no photos how I've done this)

4. Repaste your CPU and GPU (or change thermal pad on GPU if you have one)

5. And finally assembly your notebook.

DONE!

Check next post for results of this 'mod' !

 

Effect of this work:

x	before	afer	after + cooling pad
CPU	~95 degrees	max ~81 degrees	max ~71 degrees
GPU	~98 degrees // shutdown	max ~79 degrees	max ~72 degrees

with cooling pad ( Zalman NC-2500 PLUS USB powered)


If I reach my donation goal, I will post FULL and detailed instruction how to do this

 

I had this overheating issue eventually end up killing my gpu(came with geforce gt 630m ) and I found another motherboard reversion from some seller in china, this issue wasn't there anymore... I guess Acer fix that issue with reversion... I think is a faulty motherboard. I still have this laptop my gf use it is a good laptop.

 

I'll try this...my warranty expired already!

 

And I'm thinking of drilling small holes instead of cutting it

 

Could you upload the pictures again, I can not see them ¿?

Thanks

 

Today i will make on my Acer 5750G the same thing ,but with holes with a drill. later i can upload some pictures

 

so guys i didn't manage to make the holes like i sayd , but i made other thing , i have a cooling pad , and overclock on the GPU coreclock: 830Mhz and memory clock : 1030Mhz and before was 93+ degree on high graphics games, after that i clean the fan , then i put a Thermal Paste : Arctic MX-4 that i buy from ebay for just 6 euro , than i change the power suply of the cooling pad from USB(5V) to 9 V , and i manage to get even on stess test no more than 77 degree. By the way i am with i5 turboboost 2.7 GHZ (2.9 Ghz on one core) and Nvidia GT540M

 

¿could anyone repost the pic?

 

Anyone please repost the pics, i cant open.

 

Well, I drilled 5mm holes based on the pic (instead of just cutting out the whole) and mysteriously the BSODs are gone. I'll be testing for a while to be sure, that overheating was my problem.

 

I cut those wholes exactly like on the picture, but my heat stayed the same 90ish and still keeps throttling ... I've just changed the thermal paste, there is no dust in the laptop and im using a cooling pad + i'm using Acer FanControll to keep my fan at max speed, but still overheats and throttles in like 2 minutes. Could someone help ?

PS! All of those "attachments" are broken.

 

Acer have released a Fan Control Utility, once downloaded onto your desktop, it allows two options, NORMAL (i.e current setting), and FULL (fan runs continuous at 100%) great for gaming. Dropped my temps by 10 c i5 and GT540. You might have to update your BIOS they recommend version1.21. Also released for 5755G. Go to Acer Community, you might have to trawl through 20-30 pages to find the links .
