3/4) 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 CPU/system fan cable to the CPU_FAN/SYS_FAN connector to
prevent the CPU/system from overheating and failure.
