Fan Headers; Sata 3Gb/S Connectors - Gigabyte GA-78LMT-S2 User Manual

3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 3-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 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.
5) SATA2 0/1/2/3/4/5 (SATA 3Gb/s Connectors, Controlled by AMD SB710 South Bridge)
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 SB710 South Bridge 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.
