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.
