Despite what my signature says, i've been running the CPU at its default 3.0ghz speed when i dont need the extra power. I played a few games of UT and downloaded a bunch of files today. The computer was on for about 3hours so far tops, and the cpu has reached such a high temperature at default speeds. Im currently using a ThermalTake spark7 (regular edition) cooler which is supposed to be able to handle prescott cpus as high as 3.6ghz.

I know prescotts run hot, but is 78 degrees celcius an acceptable temperature for this CPU or is it going to end up in an early grave? please help, thanks
