Technical Reference Booklet
Fan Power Connectors: CPUFAN1/SYSFAN1
The CPUFAN1 (processor fan) and SYSFAN1 (system fan) support system
cooling fans using +12V via a 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 +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.
Power LED: D55/D56 (optional)
The green LED lights when the system is in the power-on state.
The red LED lights whenever AC power is attached, irrespective of whether the
system is powered-on, powered-off or in standby mode.
