3/4) CPU_FAN/SYS_FAN1/2/3/4 (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 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.

The fan/pump header is 4-pin and possesses a foolproof insertion design. 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. The header also provides speed control for a water cooling pump, refer to Chapter 2,
"BIOS Setup," "Smart Fan 6," for more information.
