The fan/pump header is 4-pin and possesses a foolproof insertion design. 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. The header also provides speed control for a water cooling pump, refer to Chapter 2, "BIOS Setup,"
"M.I.T.," for more information
