Fan Power Connectors: CFAN1/SFAN1/PSFAN1
The CFAN1 (processor fan), SFAN1 (system fan) and PSFAN1
(power supply 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.

to the actual CPU temperature.
