The CPUFAN2 (processor fan), SYSFAN1 (system fan 1), NBFAN1 (NorthBridge
Chipset fan) and PWRFAN1 (power fan) support system cooling fan with +12V. It
supports four/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

has a System Hardware Monitor chipset on-board, you must use a specially de-
