CPU FAN / SYS 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.
