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_FAN2 Pin No. 1 2 3 4 Definition GND Voltage Speed Control Sense PWM Speed Control 1 SYS_FAN3 Connector CPU_FAN SYS_FAN1~3 Maximum Current 2A 2A Maximum Power 24W 24W •• Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheating.
