Fan Power Connector: CPUFAN1, SYSFAN1
The fan power connector supports system cooling fan 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.
Important
Please refer to the recommended CPU fans at processor’s official web-
site or consult the vendors for proper CPU cooling fan.
Fan cooler set with 3- or 4-pin power connector are both available for
CPUFAN1.
