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/SYS_FAN2) and a 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.

• 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.
