3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 4-pin system fan header (SYS_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 speed control function requires
the use of a 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.
