3/4/5) CPU_FAN/SYS_FAN1/SYS_FAN2/PWR_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), a 4-pin (SYS_FAN1) and a 3-pin (SYS_FAN2)
systemfanheaders,anda3-pinpowerfanheader(PWR_FAN).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.
