6) 3_FANS_2 (System Fan/Water Cooling Pump Extension Cable Header)
Connect the included fan extension cable to this header. The cable can be used to connect up to three system
fans/water cooling pumps. 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.
7) CPU_OPT (CPU Fan/Water Cooling Pump Header)
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.
