3/4) CPU_FAN/SYS_FAN1/2/3 (Fan Headers)
All fan headers on this motherboard 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.

5) SYS_FAN4_PUMP (System Fan/Water Cooling Pump Header)
The fan/pump header is 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.
