• 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.

3/4) CPU_FAN/SYS_FAN (Fan Headers)

The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 3-pin system fan header

(SYS_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/system fan speed control, which requires the use of a CPU/system

fan with fan speed control design. For optimum heat dissipation, it is recommended that a system

fan be installed inside the chassis.
