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.
Be sure to connect fan cables to the fan headers to prevent your APU and system from overheating. Over- •
heating may result in damage to the APU or the system may hang.
These fan headers are not conguration jumper blocks. Do not place a jumper cap on the headers. •

5) SATA2_0/1/2/3(SATA3Gb/sConnectors)
The SATA connectors conform to SATA 3Gb/s standard and are compatible with SATA 1.5Gb/s standard.
Each SATA connector supports a single SATA device. The AMD A55 Chipset supports RAID 0, RAID 1,
RAID 10, and JBOD. Refer to Chapter 4, "Conguring SATA Hard Drive(s)," for instructions on congur-
ing a RAID array.
Please connect the L-shaped end of
the SATA cable to your SATA hard
drive.

• A RAID 0 or RAID 1 conguration 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 conguration requires four hard drives.
