5/6) CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3/SYS_FAN4 (Fan Headers) The motherboard has a 4-pin CPU fan header (CPU_FAN), three 4-pin (SYS_FAN1~SYS_FAN3) and a 3-pin (SYS_FAN4) system fan headers. Most fan headers possess a foolproof insertion design. When con- necting 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.
