2.3.8 CPU_FAN/SYS_FAN (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 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.
