3/4/5) CPU_FAN / SYS_FAN1 / SYS_FAN2 / SYS_FAN3 / PWR_FAN (Fan Headers)<br />
The motherboard has a 4-pin CPU fan header (CPU_FAN), a 4-pin (SYS_FAN2) and two 3-pin<br />
(SYS_FAN1/SYS_FAN3) system fan headers, and a 3-pin power fan header (PWR_FAN). Most fan<br />
headers possess a foolproof insertion design. When connecting a fan cable, be sure to connect it in<br />
the correct orientation (the black connector wire is the ground wire). The motherboard supports CPU<br />
fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum<br />
heat dissipation, it is recommended that a system fan be installed inside the chassis.<br />

6) NB_FAN (North Bridge Fan Header)<br />
Connect the North Bridge fan cable to this header. The fan header has a foolproof insertion design.<br />
When connecting a fan cable, be sure to connect it in the correct orientation. Most fans are designed<br />
with color-coded power connector wires. A red power connector wire indicates a positive connection<br />
and requires a +12V voltage. The black connector wire is the ground wire.<br />

• Be sure to connect fan cables to the fan headers to prevent your CPU, North Bridge and<br />
system from overheating. Overheating may result in damage to the CPU/North Bridge or<br />
the system may hang.<br />
• These fan headers are not configuration jumper blocks. Do not place a jumper cap on the<br />
headers.<br />
