3/4) CPU_FAN/SYS_FAN1/2/3 (Fan Headers) The motherboard has a 4-pin CPU fan header (CPU_FAN), two 4-pin (SYS_FAN1, 2) and one 3-pin (SYS_ FAN3) system fan headers.. 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/SYS_FAN2 CPU_FAN/SYS_FAN2: Pin No. Definition 1 GND 2 +12V 3 Sense 4 Speed Control 1 SYS_FAN1 SYS_FAN1: Pin No. 1 2 3 4 Definition GND +12V / Speed Control Sense VCC 1 SYS_FAN3 SYS_FAN3: Pin No. Definition 1 GND 2 +12V 3 NC DEBUG PORT •• Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheating.

FAN3) system fan headers.. 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.
