Fan Power Connectors: CFAN1/SFAN1/PSFAN1/NBFAN1

The CFAN1 (processor fan), SFAN1 (system fan), PSFAN1 (power sup-
ply fan) and NBFAN1 (chipset fan) support system cooling fan with +12V. It
supports three-pin head 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 Monitor chipset on-board, you
must use a specially designed fan with speed sensor to take advantage of the
CPU fan control.

ing to the actual CPU temperature.
