Fan Power Connectors: PFAN1/SFAN1

The PFAN1 (processor fan) & SFAN1 (system fan) connectors provide +12V

power supply for the system cooling fan, via a three-pin connector. When

connecting the wire to the connectors, always take note that the red wire is the

positive and should be connected to the +12V, the black wire is Ground and

should be connected to GND. If the mainboard has a System Hardware Moni-

tor chipset on-board, you must use a specially designed fan with speed sensor

to take advantage of the CPU fan control.

NOTE: Always consult the vendor for proper CPU cooling fan.
