3/4/5) CPU_FAN/SYS_FAN/PWR_FAN (Fan Headers)

The motherboard has a 4-pin CPU fan header (CPU_FAN), a 4-pin system fan header (SYS_FAN), and a 3-pin power fan header (PWR_FAN). Each fan header supplies a +12V power voltage and possesses a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation. Most fans are designed with color-coded power connector wires. A red power connector wire indicates a positive connection and requires a +12V voltage. The black connector wire is the ground wire. The motherboard supports CPU fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.

6)NB_FAN (North Bridge Fan Header)

Connect the North Bridge fan cable to this header. The fan header has a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation. Most fans are designed with color-coded power connector wires. A red power connector wire indicates a positive connec- tion and requires a +12V voltage. The black connector wire is the ground wire.

•Be sure to connect fan cables to the fan headers to prevent your CPU, North Bridge and

system from overheating. Overheating may result in damage to the CPU/North Bridge or the system may hang.

•These fan headers are not configuration jumper blocks. Do not place a jumper cap on the

headers.
