3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 4-pin APU 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.
• Be sure to connect fan cables to the fan headers to prevent your APU and system from overheat-
ing. Overheating may result in damage to the APU or the system may hang.
• These fan headers are not configuration jumper blocks. Do not place a jumper cap on the headers.
5) SATA3 0/1/2/3 (SATA 6Gb/s Connectors)
The SATA connectors conform to SATA 6Gb/s standard and are compatible with SATA 3Gb/s and SATA
1.5Gb/s standard. Each SATA connector supports a single SATA device. The AMD A75 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.
• A RAID 0 or RAID 1 configuration requires at least two hard drives. 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.
