Hardware Setup
Fan Power Connector: CPUFAN1, SYSFAN1
The fan power connectors support 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.
