Maximum CPU operating temperature
I have a P4 2.4GHz 800MHz processor, and I was jus wondering what temperature the processor should never go above, so a maximum operating temperature if you will. Apparently P4's use a technology whereby the higher the temperature of the CPU the slower it will go, it's designed to do this. They say you can run it without a heatsink, but we aren't that crazy. Anyway, that's my question. What temperature should I try run it at without losing performance. While we're at it, what should I keep the system temperatures below? Thanks.

I think the P4s are designed to throttle back if the temps reach 65 or 70 C. Keep the temps below 60 C and you should be fine.

PIII's don't throttle, but are thermally protected and will just halt the system if overheated. I forgot to plut in the CPU fan on a 900Mhz Celeron once and it ran fine for a week at 90'C+. No slowdowns, no lockups, but dang was that heatsink hot.
Of course I don't recommend running that hot... but if you keep it below 60'C as Cricket suggested, it will be fine. My Celeron 1100 runs at 54'C under a 100% CPU load 24/7.
