3/4) CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3 (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) CPU_OPT (Water Cooling CPU 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). 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.
•
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.
