took my laptop apart, cleaned the fans thoroughly and applied new thermal paste to the cpu and gpu to try and fix an overheating problem ive been having. 0 effect... im running a qosmio x875 q7380 for reference and this thing only has a single copper pipe running to the laptops only fan to cool the cpu no heat sink whatsoever. is there another solution to my heating problem that i can explore other than cooling pads because there isnt enough ventilation on the bottom of the laptop for a cooling pad to be effective. Im getting temps in the 105C range playing csgo, thats how bad this issue is. I can limit fps to 60 using dxtory and disable multicore rendering to drop it to about 85C but its still not the solution im looking for.

Couple of questions if I may;

What type of overheating problems have you been having as in shutting down unexpectedly or artifacting as a couple of examples.
Is the problem the same on battery only power and with the battery removed and the AC adaptor powering the computer.
Is it the original battery, if not, is the replacement an exact like for like and not a cheap generic import.
Do you have the power plan set to Balanced and not High Performance.

How are you monitoring the temperatures, due to the lack of appropriate sensors that notebook MBs have programs such as HWMonitor and Speedfan are of very little use and the readings not relied on.

The laptop shuts down, ive tested it on battery and off while plugged in and its having the same effect. The battery is original and the powerplan is set to balanced. I had it set to high performance and they both do the same thing. I do use both speedfan and HWMonitor, i havent had any reason to not believe the data given by them. They both tell me it idles at around 59C on desktop with nothing open and quickly shoots up to like 70C just running netflix in browser. This problem didnt occur until about a year and a half after i purchased the laptop though so I immediately came to the conclusion that it just needed cleaning out. I read on some amazon page for this laptop that another person fixed their overheating problem with a bios rollback but he doesnt mention which version he rolled back to.

Thanks for the update skarci (y)

Couple of additional questions for you;

What OS are you running.
Have you tried the Power saver option.
What did you use to clean off the old thermal compound and what was the new thermal compound that was applied.

Only two things that I can think of that could be changed by another version of BIOS is the MB voltages and thermal parameters, we should take a look at the latter at some point.

im running windows 10 64 bit, i havent tried power saver yet and i used 91% isopropyl alcohol and coffee filters to clean the old thermal compound off. the new thermal compound is arctic mx4

edit: I tried powersaver mode, it helps a little with temps but the cut in performance when running games is pretty bad. im getting about 20 fps max.

Im gunna try something like this and hope for the best but i dont know how well its going fit because the fan vent is right next to where the power gets plugged in

also found a list of all the bios versions available

im not an expert on flashing bios so im not going to just start trying to change them without researching which version would possibly fix my issue

Hi Buddy (y)

you could mod it with copper shim on the GPU and CPU see if any better...

the videocard has its own heatsink, the processor has nothing more than a copper plate with a heatpipe connected to it running to the fan. its just the processor thats overheating. the videocard is consistently 10-15C lower than the processor

Job done as it should be and with a proven good TIM product reapplied so that is possibly ruled out.

Not seeing anything listed in those BIOS updates specifically to address a known overheating CPU problem but fwiw the most recent BIOS release includes all of the previous versions.

You most likely have both of the following installed already but please see my canned info below;

Please take expanded screenshots and only use the method below to attach them.

Download Speedfan from here and install it. Once it's installed, run the program and post here the information it shows. The information I want you to post is the stuff that is circled in the example picture I have attached.

If you are running on a vista machine, please go to where you installed the program and run the program as administrator.

(this is a screenshot from a vista machine)


Download then run HWMonitor and post a screenshot so that we have a comparison to the Speedfan results, details from here


To capture and post a screenshot;

Click on the ALT key + PRT SCR key..its on the top row..right hand side..now click on start...all programs...accessories...paint....left click in the white area ...press CTRL + V...click on file...click on save...save it to your desktop...name it something related to the screen your capturing... BE SURE TO SAVE IT AS A .JPG ...otherwise it may be to big to upload... Click on the More Reply Options tab then after typing in any response you have... click on Upload a File...desktop...find the screenshot..select it...click on Post reply like you normally would.

Screenshot instructions are provided to assist those that may read this topic but are not yet aware of the “how to”.

This is with no other programs open and I let it idle for a few mins before taking the ss. I understand that laptops normally dont idle at ~30C like a well cooled desktop but even a 15% load on the processor is causing the temps to shoot up to 75C+

This is after about 10 minutes in CS:GO with balanced power mode and low graphics settings

When I originally got this laptop I was playing games like planetside 2 on max settings getting great fps for hours at a time and had 0 shutdowns from overheating. I cant say exactly whats going wrong with this system now, I remember the first overheating problem I had was when I attached a second monitor to the laptop for the first time and the system shut down after about 2 minutes of use. Since then I havent used any extra monitors with it.

Thanks for comprehensive update skarci (y)

Those readings look normal for a notebook when under load and apparently for the i7 3630QM as it is known to run hot, not finding any suggestions anywhere as how to help cool the CPU down any better than what you have done already so my suggestion would be to try and cool down the air that the internal cooling fan is drawing in, directing a desktop fan (one either side of the vents would be better) would be a good starting point.

You have most likely read this already but an Intel agent gives a reply on the high temps of the i7 3630QM here the notebook concerned is an Acer and another thread here where the notebook is a HP, it would appear that yours is not an isolated case.
