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_FAN2) and a 3-pin (SYS_FAN1)
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.
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 conguration jumper blocks. Do not place a jumper cap on the headers. •
