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.
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).
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.
