3/4) CPU_FAN/SYS_FAN (Fan Headers)
The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 4-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 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 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. 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.

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.
