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.
