3/4/5) CPU_FAN/SYS_FAN1/SYS_FAN2/PWR_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN), a 4-pin (SYS_FAN1) and a 3-pin (SYS_FAN2)
system fan headers, and a 3-pin power fan header (PWR_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 speed control function 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 CPU and system from
overheating. Overheating may result in damage to the CPU or the system may hang.
• These fan headers are not configuration jumper blocks. Do not place a jumper cap on the headers.
6) SATA3 0/1/2/3/4/5 (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 South Bridge supports
RAID 0, RAID 1, RAID 5, RAID 10, and JBOD. Refer to Chapter 3, "Configuring a RAID Set," for instructions
on configuring a RAID array.
