CPU FAN / SYSTEM 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 fool-proof 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.
