6) SYS_FAN5/6_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. Please navigate to the "BIOS Setup" page of GIGABYTE's website and search for "Smart Fan 6" for more information. 1 SYS_FAN6_PUMP 1 SYS_FAN5_PUMP Pin No. 1 2 3 4 Definition GND Voltage Speed Control Sense PWM Speed Control •• Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheating.
