fan power Connectors - Cpu faN / sys faN1 / sys faN2(optional)
The CPUFAN (processor fan), SYS FAN1, SYS FAN2 support system cool-ing
fans using +12V via a 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 motherboard 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.
