Hi all, I am trying to set up speedfan on my new board. Can anyone tell me what "Temp3" and "Temp1" refer to? Also, is "Fan03" the little 40mm one that cools the capacitors? Thanks!

It's looking like temp3 is the NB? Does anyone agree with that?

Doesn't PWM stand for pulse width modulation? How does that have to do with a fan speed monitored in speedfan?
The PWM is the switching regulator circuit for the CPU voltage and it is one of the hottest sections of the motherboard. It is also what is connected to the third temperature sensor input of the Winbond Super I/O chip. The registers Winbond chip are what programs like Speedfan, MBM and the BIOS read to get the temperature values they report.

so is that for temp1 or temp3? If you said "voltage regulating chip" I would have got it 
thanks!
thanks!

Okay Figured out by comparing speeds in BIOS that Fan03 is the OTES fan.

and you are correct, one is for the PWM circuit and the other reads system temps, not to figure out which is which.
