|Hi I have the same problem more or less, according to intel's website the thermal spec for my 3.00Ghz Prescott P4 is 69.1 C.|
I have not tinkered with the settings nor overclocked this P4 it just seems to run hot.
When idle my CPU temp is about 59-64C however when running games or some other applications it jumps to around 74-78C, but my system temperature remains at a nice 27C.
These temperature fluctuations were occuring with the stock heatsink and fan installed which should have been able to cope, but obviously couldn't so just to test I went out and bought a Cooler Master D14-8KD3B-0L heatsink and fan, for P4's 3.6GHz or higher...
Sadly it has made no difference whatsoever and I am concerned for the health of my PC.
