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 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.

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

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.
