I though the motherboard one on Asus probe was the PWM temp.
Pulse Width Modulation...usually associated with power being applied to fans -on and off very quickly to give the appearance of slowing the fan down using the usual voltage reduction.
In this case it is referring to how hard the mosfets on the board have to work to keep up with the level of power draw. Important for overclocking. You see these mosfets near the base of the cpu socket. Also around the motherboard in different places. 8 phase power mobos will have 8 of them. They get very very hot. On abit boards 80 degrees is where Abit say you should stay under. But they are certified to work up until 150 degrees. Overclocking dual cores, especially Intel extremes causes them to heat up big time as does faulty or poor quality psu's. My ones got to 110 degrees !!, until I decided to overclock my cpu using the multiplier instead of the front side bus which allowed me to lower the voltage and keep the pwm temps below 70. Now at 4.8ghz on my cpu and smiling
