3/4/5) CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3/PWR_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), a 4-pin (SYS_FAN3) and two 3-pin (SYS_
FAN1/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 motherboard supports CPU fan speed con-
trol, 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.
Be sure to connect fan cables to the fan headers to prevent your CPU, Chipset and system from •
overheating. Overheating may result in damage to the CPU/Chipset or the system may hang.

6) PCH_FAN (Chipset Fan Header)
Connect the Chipset 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 connection and requires a
+12V voltage. The black connector wire is the ground wire.
