4 cpu_fan sys_fan fan headers 17
All fan headers on this motherboard are 3 pin 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 17
