Acer 5755G Overheating

Hoping this thread is placed right.
'That being said, i'm having heat problems with my laptop. After 20 min. of low demanding gaming, the temp of my GPU gets to 90 c, and can sometimes get up to 95 c. To me it seems high!!

The specs. is as follows; Intel Core i7-2670QM 2,2 and GeForce GT 630M
It's basically been like this since i got my comp. so i figured it was kind of normal - which also means that it proabably won't have any effect to clean it from dust.

I'm hoping for some comments.

 

cleaning is your first step. has to be done evry 2-3 months
BUT if its been doing it from new it most prob needs new thermal paste on the gpu BUT before you try that make sure all the screws are done up tight as if they are not then that could be your problem.

what temps are you getting from the cpu and also what are you using to monitor your temps.

lots of monitoring tools in sig below.

 

HW Monitor CPU/ID for the CPU, and for the GPU,, The CPU is the same, like 85 c

 

Those are high temps for those specs; what "low demanding gaming" are you doing?. I think Acer uses cheaper components to keep costs down, so even if you clean and were to have things repasted, your temps may only drop slightly. Keep in mind too that the ambient temperature plays a role in your temps as well.

If you don't have a chill pad already, you might want to look into one. Modding the cooling system could help, but don't do anything that voids your warranty if you're still covered (that includes opening it to clean it).

 

sitting in a fridge sounds like a good idea

 

Put a pencil or something of similar height under the back of the notebook to get it slightly off the surface and see how that affects temperatures.

Your notebook is probably not straightforward to take apart, but effectively reapplying thermal compound could help reduce temperatures a few deg. C (read: will not make the difference you're looking for, unless Acer applied the paste wrong in the first place which isn't likely). Historically I've used Arctic Silver 5 with good results.

A cooling pad is the next step. My advice is to find one that blows air at the bottom of the notebook (one that doesn't suck, and I mean that in more ways than one). I had an Acer many years ago and it had heating problems. My final solution was a cooling pad.

After that there's conventionally not much you can do aside from making some copper shims to help make the heatsinks more effective.

Here's a cooling guide I wrote nearly seven years ago that still holds some good advice:
Guide to Cooling Down Your Notebook Computer

 

If you want to take the re-paste route, I found a disassembly guide for 5750G model, it's similar model to yours but may be with some minor deviations. HTH.

Thanks alot guys/girls!!

I especially liked the advice that had to do with sitting in a fridge.
Sounds like it won't get below 80 c, which i was hoping for.
I cleaned it, and i already have a decent coolingpad, so i guess i will have to settle with the 98 c from time to time.
But thanks a lot!

 

You're bound for throttling with those temps, and potential chip creep if you let it cool off frequently (especially from shutting it down after doing your gaming).

Be careful. If you getting those temps after cleaning, with a cooling pad, then it probably needs new compound.
