3) CPU_FAN (Fan Header)
The fan header is 4-pin and possesses 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.

4) FAN1_PUMP (Fan/Water Cooling Pump Header)
The fan/pump header is 4-pin and possesses 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.
