If you are using set6x86 to enable hlt mode then those should be very cool
to the touch. Boot Win95 or remove it. When you compile a kernel it warms
up everything (power usage rises to 10-20Watts) because the processor is
no longer in suspend mode, which uses very little power.

Basically if you are having cooling problems then you should try to get it
as hot as possible and then do what you can to cool it down until it
stops failing then turn on the suspend features. That will give you a
pretty good assurance that it will not fail.

I am lucky in that the 3 large heat sinks on the voltage regulators are
directly beside the cpu so some of the air motion generated by the cpu fan
spills over onto the heat sinks, I have even heard of special fans that
increase this. Another thing you might want to do is to put another fan in
the front section of the case blowing air in
