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).
Each fan header supplies a +12V power voltage and possesses a foolproof insertion design. When con-
necting a fan cable, be sure to connect it in the correct orientation. Most fans are designed with color-
coded power connector wires. A red power connector wire indicates a positive connection and requires
a +12V voltage. The black connector wire is the ground wire. The motherboard supports APU fan speed
control, which requires the use of a 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 configuration jumper blocks. Do not place a jumper cap on the headers.

5) SATA3_0/1/2/3/4/5 (SATA 6Gb/s Connectors, Controlled by AMD A75 Chipset)
The SATA connectors conform to SATA 6Gb/s standard and are compatible with SATA 3Gb/s and SATA
1.5Gb/s standards. Each SATA connector supports a single SATA device. The AMD A75 Chipset sup-
ports RAID 0, RAID 1, RAID 10, and JBOD. Refer to Chapter 4, "Configuring SATA Hard Drive(s)," for
instructions on configuring a RAID array.
Please connect the L-shaped end of
the SATA cable to your SATA hard
drive.

• 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.
