3/4) CPU_FAN/SYS_FAN (Fan Headers) The motherboard has a 4-pin CPU fan header (CPU_FAN), a 4-pin system fan header (SYS_FAN). 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. 1 CPU_FAN 1 SYS_FAN CPU_FAN/SYS_FAN:: Pin No. Definition 1 GND 2 +12V 3 Sense 4 Speed Control •• Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheating. 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 jumper cap on the headers. 5) SATA2 0/1/2/3 (SATA 3Gb/s Connectors) DEBUG PORT DEBUG PORT DEBUG PORT DEBUG PORT The SATA connectors conform to SATA 3Gb/s standard and are compatible with SATA 1.5Gb/s standard.
