Since switching from Windows 7 to Fedora 16, my laptop has been running incredibly hot (by the air exhaust). The laptop is an Asus K73S.

Running sensors, I receive:

acpitz-virtual-0: 75.0 celsius
nouveau-pci-0100: 66.0 celsius
asus-isa-0000: 75.0 celsius

The only CPU hog is Firefox at 30 - 40% on average.

My GPU information (from lspci) is: Intel Corporation Xeon E3-1200/2nd Generation Core Process or Family Integrated Graphics Controller (rev 09).

Running lspci | grep -i VGA, returns:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: nVidia Corporation GF106 [GeForce GT 555M SDDR3] (rev a1)

I don't notice a huge difference running without the battery, but it does seem a little cooler.

1) What is your question? 2) 75C is not that hot... – soandos Jul 1 '12 at 5:34
My question is how come it is running so hot / how do I make it not run as hot? It's too hot to hold on my lap or have anything near the exhaust. – sdasdadas Jul 1 '12 at 5:40
If your computer is getting so hot that it's uncomfortable to handle, you most likely have a hardware problem. – David Schwartz Jul 1 '12 at 8:19

It might be you have been collecting dust overtime, this reduces the cooling capabilities. Dust it out.

Also try this:

echo low > /sys/class/drm/card0/device/power_profile

That would not be OS dependant.... – soandos Jul 1 '12 at 5:42
It might not be OS dependent at all, I thought the might be elsewhere. – Lucas Kauffman Jul 1 '12 at 6:07
That will be OS dependent because different OSes have different power management algorithms. The most likely explanation is dust or a failed/failing fan. – David Schwartz Jul 1 '12 at 8:20
