2) SYS_FAN (Fan Header)

The fan header on this motherboard is 4-pin. The fan header possesses 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.

• Be sure to connect fan cables to the fan headers to prevent your CPU and system from

overheating. Overheating may result in damage to the CPU or the system may hang.
