Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheating. Over-
•
heating 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.

3/4) CPU_FAN/FAN1/FAN2/FAN3/FAN4 (Fan Headers)
All fan headers on this motherboard are 4-pin and support fan speed control function. 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.
