4/5) CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3 (Fan Headers)
All fan headers on this motherboard are 4-pin. 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.

• 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.
