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 (CPU_FAN/
SYS_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).
Remember to connect the CPU/system/power fan cable to the CPU_FAN/SYS_FAN/PWR_FAN
connector to prevent CPU damage or system hanging caused by overheating.
