3/4) CPU_FAN/SYS_FAN (Fan Headers) The motherboard has a 4-pin CPU fan header (CPU_FAN) and 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 APU fan speed control, which requires the use of a APU 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 SYS_FAN: Pin No. Definition 1 SYS_FAN 1 GDNEBDUG 2 +P1O2RVT/Speed Control 3 SDPeOEnBRsUTeG 4 RDeEsBeUrGve PORT •• Be sure to connect fan cables to the fan headers to prevent your APU and systeDmEBfUroGm overheating.

Each SATA connector supports a single SATA device. The AMD A75/A55 Chipset supports RAID 0, RAID 1, RAID 10, and JBOD. Refer to Chapter 4, "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. - 16 -
