This laptop has always had this problem. The temperatures kick up to the thermal ceiling of 99C for the CPU (i7-3610QM) and 94C for the GPU (GT 640M). Problem is, the FAN doesn't give a damn. It's actually QUIETER when the temperatures are that high, than when it's at 60C or so. I figured it was a problem with the BIOS, so I updated that, no change. So maybe it was a problem with windows? Nope, same result on gaming with Ubuntu.

The major problem of this, is that after gaming for ten minutes the CPU throttles itself to 1197MHz(as opposed to 3193), and the GPU goes down to 135MHz( as opposed to 843MHz).

The problem is that the fan won't kick in like I know it can, because when the laptop is in POST, like at BIOS setup, the fan is like a vacuum cleaner it's so loud! I don't really care about noise, so I'd love to have the fan like that all the time as long as the temperatures don't fly through the roof...

So, things I've tried so far, to avoid possible duplicate answers.

  • Checked for dust: It's been this way since the laptop was new, and I've since then taken it apart. No dust buildup.
  • Background stuff running?: No, problem persists across OS'es, and it happens while gaming anyways
  • Manually underclocking both CPU/GPU: Using windows, I can force the CPU to stay at 1.1GHz, but the temperature STILL easily hits 99C after 5 min of gaming
  • Contacted Acer support?: No help at all. They told me to update and reset the BIOS, which I have done multiple times. There are only about 6 changeable things anyway, none of which should affect the FAN control
  • Third party fan control program?: None detect the fan

So, I'm screwed until I can afford to replace this laptop, but I am very satisfied with performance in games... Whenever the CPU/GPU aren't being throttled.

Anyone that can offer advice to solve this problem would be greatly appreciated. Hell, if you solved my problem I'd send you some monies through paypal.
