6) SYS_FAN5_PUMP/SYS_FAN6_PUMP (System Fan/Water Cooling Pump Headers)
The fan/pump headers 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 dis-
sipation, 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," "Settings\Smart Fan 5," for more
information.
