Just put together a new system with a P4C and I've noticed that with HT on the CPU runs considerably cooler. As reported by ASUS Probe, with HT on my CPU/Mobo temps are 30/39, with HT off temps are 38/41. After 15 minutes of full load (the temps maxed out after the first 5 minutes of full load so I don't think running it any longer would make much difference) is 43/44 'off', and 44/45 'on', so not much of a difference there. But idle temps are what really shocked me.
Also, I've noticed that with HT on cpu voltage is slightly higher (1.568v 'off', 1.616 'on'). Have other people also noticed these voltage/temp differences? I tried switching HT on and off a few times to double and triple check the temps, each time letting it sit for a good while to make sure it reached idle temp, and the results were the same every time.
