I bought a pretty decent setup, but it is not doing me any good as long as I have this pesky heat problem.

I have a P4 3 GHz with 512 400 MHz memory, 400w power supply, and the default heatsink and fan for the CPU. The case has front and back fans, and I removed some of the add-on cards I do not use.

However, it is still running at a whopping 70~75c!!! I have never seen a P4 run this hot. What else could be causing it?

Thanks
