3/4) CPU_FAN/SYS_FAN (Fan Headers) The motherboard has a 4-pin CPU fan header (CPU_FAN), a 3-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 CPU_FAN: Pin No. Definition 1 GND 2 +12V /Speed Control 3 Sense 4 Speed Control 1 SYS_FAN SYS_FAN: Pin No. Definition 1 GND 2 +12V 3 Sense DEBUG PORT DEBUG PORT •• Be sure to connect fan cables to the fan headers to prevent your CPU and system fromDoEvBeUrhGeating.

Each SATA connector supports a single SATA device. The AMD SB710 South Bridge supports RAID 0, RAID 1, RAID 10, and JBOD. Refer to Chapter 5, "Configuring SATA Hard Drive(s)," for instructions on configuring a RAID array.

If more than two hard drives are to be used, the total number of hard drives must be an even number. • A RAID 10 configuration requires four hard drives. Please connect the L-shaped end of the SATA cable to your SATA hard drive. - 15 - Hardware Installation
