Fan Headers; Sata 6Gb/S Connectors - Gigabyte GA-990FXA-UD3 User Manual

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 3-pin (SYS_FAN2) and a 4-pin (SYS_
FAN1) 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 motherboard supports CPU fan speed control, which
requires the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recom-
mended that a system fan be installed inside the chassis.
6) SATA3_0/1/2/3/4/5 (SATA 6Gb/s Connectors, Controlled by AMD SB950 South Bridge)
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 SB950 South Bridge
supports RAID 0, RAID 1, RAID 5, RAID 10, and JBOD. Refer to Chapter 5, "Configuring SATA Hard
Drive(s)," for instructions on configuring a RAID array.

Hardware Installation
Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheating. Over-
•
heating 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.

• 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 5 configuration requires at least three hard drives.
(The total number of hard drives does not have to be an
even number.)
• A RAID 10 configuration requires four hard drives.
