3/4) CPU_FAN/SYS_FAN1/2/3 (Fan Headers) All fan headers on this motherboard are 4-pin. Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation (the black connector wire is the ground wire). The speed control function requires the use of a fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis. 1 CPU_FAN 1 SYS_FAN1/SYS_FAN3 1 SYS_FAN2 Pin No. 1 2 3 4 Definition GND Voltage Speed Control Sense PWM Speed Control 5) CPU_OPT (Water Cooling CPU Fan Header) The fan header is 4-pin and possesses a foolproof insertion design.
