Hardware Installation
• Be sure to connect fan cables to the fan headers to prevent your CPU and system from
overheating. Overheating may result in damage to the CPU or the system may hang.

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
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.
