  • Page 20 1/2/6/20/21/22) SYS_FAN4/SYS_FAN5/CPU0_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3 (FAN Headers) The motherboard has one 4-pin CPU fan header (CPU_FAN), and five 4-pin (SYS_FAN) system fan headers. 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 motherboard supports CPU fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.
