3/4/5) CPU_FAN / SYS_FAN / PWR_FAN (Cooler Fan Power Connector)
The cooler fan power connector supplies a +12V power voltage via a 3-pin/4-pin (only for
CPU_FAN) power connector and possesses a foolproof connection design.
Most coolers are designed with color-coded power connector wires. A red power connector
wire indicates a positive connection and requires a +12V power voltage. The black connector
wire is the ground wire (GND).
Please remember to connect the power to the cooler to prevent system overheating and
failure.
Caution! Please remember to connect the power to the CPU fan to prevent CPU overheating
and failure.
6) NB_FAN (Chip Fan Connector)
If you installed wrong direction, the chip fan will not work. Sometimes will damage the chip fan.
(Usually black cable is GND)
