3/4) CPU_FAN/SYS_FAN1/SYS_FAN2 (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 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) SATA3 0/1/2/3 (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. The SATA connectors support RAID 0, RAID 1, and RAID 10. Refer to Chapter 3,
"Configuring a RAID Set," for instructions on configuring a RAID array.
6) SPDIF_O (S/PDIF Out Header)
This header supports digital S/PDIF Out and connects a S/PDIF digital audio cable (provided by expansion
cards) for digital audio output from your motherboard to certain expansion cards like graphics cards and
sound cards. For example, some graphics cards may require you to use a S/PDIF digital audio cable for
digital audio output from your motherboard to your graphics card if you wish to connect an HDMI display
to the graphics card and have digital audio output from the HDMI display at the same time. For information
about connecting the S/PDIF digital audio cable, carefully read the manual for your expansion card.
