Fan Power Connectors: CPUFAN/SYSFAN/PSFAN
The CPUFAN (processor fan), SYSFAN (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.
