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.
• 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.
• These fan headers are not configuration jumper blocks. Do not place a jumper cap on the headers.
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.
