5/6) CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3/SYS_FAN4 (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), three 4-pin (SYS_FAN1~SYS_FAN3) and a
3-pin (SYS_FAN4) system fan headers. Most fan headers possess a foolproof insertion design. When con-
necting 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.
7) 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). 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 overheat-
ing. 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.
