3/4) CPU_FAN/SYS_FAN1 (Fan Headers)

All fan headers on this motherboard are 4-pin. 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.
