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 B S_ B fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.
