Fan Power Connectors: CPU_FAN / SYS_FAN / PWR_FAN / NB_FAN
The CPU_FAN (processor fan), SYS_FAN (system fan), PWR_FAN (power fan
) and NB_FAN (NorthBridge Chipset fan) support system cooling fan with +12V. The
CPU_FAN supports four/three-pin head connector. The others support 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.
