3/4) CPU_FAN/SYS_FAN (Fan Headers)
All fan headers on this motherboard are 4-pin. 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. 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) 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, "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.
