Extreme Hot Laptop GPU? Nearly Boiling Point.

[Byamba3]

My GPU has been running fantastic although the idle temp was around 55 Celsius, and when in game it could go from 70-90 Celsius.

Now it's far worse, it has bypassed 100 C couple of times where it would just shut itself down, but never came to the point where it burned itself. I am really guessing it's because of the fan which collected lot of dust and causing my gpu to run far slower than it was at first.
My laptop case feels so hot, and I still wonder why it hasn't melted yet.
For example, 5 min in the game when the temp is at around 80C it would have good FPS, then 5 min later it would drop down about 10 fps, and when I check the temp its over 90 celcius.

It has been like this for half a year, I do gaming pretty much all the time on my laptop, I still wonder how it hasn't burned itself yet.

One thing I have to say is Acer Aspire's fanning system really sucks. The graphics card is 540m, can run latest games on medium.


I wanted to open up my laptop and clean the fan, but that's way too much work and bit risky. Would have to involve removing the monitor and keyboard to get to the fan.

But you might not have any other choice. The fan must get cleaned.

Most laptops I've seen allow you fan access by removing the back. Just a bunch of screws and you should be looking at the cooling assembly. Read the manual, pay someone if you need to. But you need to get it done.

You will either have to get it open and cleaned, or provide an external cooling system to freshen up air more efficiently to cool it down. since its aged, the thermal paste or contact might have gotten loose as well.

I am getting a new desktop now, amazing deal for $400. 3rd gen i5 3330, 8gb ddr3, gt 620.

I will then open up my laptop carefully and clean the fan.

use an air compressor to blow the dust out, disassembling the laptop just to get to a fan seems a little ridiculous.

Need to be careful with air compressor. I think some of them can blow hard enough to damage the fans. A shot from an air can should be ok. Problem is without the casing open to allow the dirt/dust to escape it won't be long before its back in the sink/fan blades. Opening it really is the best way.

i set my air compressor around 80psi, and have never had a problem in the 15+ years ive been using it. its all about short bursts. an air can just doesn't come close.
