I don't know that I would consider W2K doing nothing necessarily as being at idle

If you can find a software cooler for the P4, the Stop-Grant state of a P4 drops the power to almost 1/3 of normal.

For the stress side, try Prime95, Folding, or SETI. (Intel also has a proggy called Maxpower that generates the worst case heat load possible, but I don't remember where they hide it).

Note also that besides the auto-throttle that some motherboards have, the P4 also has an internal throttle circuit that reduces the duty cycle of the processor at a set temp. If you want to be sure this isn't going on, run SiSoft's CPU bench after a cold start and record the info. Then run a stress proggy for 30 mins, then re-run the CPU bench. If the numbers change significantly, then you are being throttled.

pHaestus - yes, relatively low. A P4 at 2.2Ghz and default Vcore is about 55W. At the 1.65 Vcore and 2.4Ghz that eX&TriC said he was running that would go up to about 73W.
