6) SYS_FAN5_PUMP/SYS_FAN6_PUMP (System Fan/Water Cooling Pump Headers)
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," "Settings\Smart Fan 5," for more information.
7) CPU_OPT (Water Cooling CPU Fan Header)
The fan 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.
• Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheat-
ing. Overheating may result in damage to the CPU or the system may hang.
• These fan headers are not configuration jumper blocks. Do not place a jumper cap on the headers.
