3/4) CPU_FAN/SYS_FAN (Fan Headers)

The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 3-pin (SYS_FAN) 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 motherboard supports CPU

fan speed control, which requires the use of a CPU 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 over-

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