S_ SF _ 3/4) CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3 (Fan Headers) All fan headers on this motherboard are 4-pin. Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure to conBn_ect it in the cSorre_cSt 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.

Overheating may result in damage to the CPU or the system may hang. •• These fan headers are not configuration jumper blocks. Do not place a ju_mper cap on the headers. _ _B 5) SATA EXPRESS (SATA Express Connector) Each SATA Express connector supports a single SATA Express device.
