Keep in mind the thermal protection in the P4 is a good thing.  Heres 
why.  The P4 won't go into this mode with the proper heatsync and fan 
attached.  But if the fan stops, or something similar that will raise the 
temperature, the processor clocks it's self down instead of frying it's 
self.  Also, the P4 puts out less heat then the Athlons currently do.
