6) SYS_FAN5A_PUMP/SYS_FAN5B_PUMP/SYS_FAN6_PUMP (System Fan/Water Cooling
Pump Headers)
The fan/pump headers are 4-pin and 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 headers also provide speed control
for a water cooling pump, refer to Chapter 2, "BIOS Setup," "Settings\Smart Fan 5," for more information.
