Hi, I am having an overheating problem on Toshiba Satellite C640. The problem is more acute after upgrading the kernel to kernel-PAE-3.6.10-2.fc17.i686.

This happens even when there are minimal applications running.

sensors output
acpitz-virtual-0
Adapter: Virtual device
temp1:        +74.0°C  (crit = +110.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +67.0°C  (high = +80.0°C, crit = +90.0°C)
Core 2:       +72.0°C  (high = +80.0°C, crit = +90.0°C)

If i start with kernel-PAE-3.6.7-4.fc17.i686 the overheating is comparatively less.

The load is also low:

What LOW load? Your memory (RAM) is used to about 95%! How old is the device?

You said the problem is more acute after upgrading the kernel. That implies it had a problem previously.

I know this sounds really basic, but have you tried blowing compressed air through the device? Also, check the BIOS to see if overclocking is turned on. You should scale that back so you don't melt down your chip.

Since this thread is a year old, can you update it with any other resolutions you've found?

Best wishes,

Rick

I had a problem like this, and blowing all the accumulated dust and crud off of the CPU heatsink and fan made the problem go away.
