5) 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.

6) SYS_FAN3_PUMP (System Fan/Water Cooling Pump Header)
The 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. 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, refer to Chapter 2, "BIOS Setup," "M.I.T.,"
for more information.

3/4) CPU_FAN/SYS_FAN1/2 (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.
•
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 coniguration jumper blocks. Do not place a jumper cap on the headers.
