Connectors
Fan Power Connectors: CPUFAN1/2/3, POWERFAN1/2/3/4
The fan power connectors support system cooling fans with +12V. When
connecting the wire to the connectors, always 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 onboard,
you must use a specially designed fan with speed sensor to take advantage of the
CPU fan control.
