Fan Headers (FAN1~4, FANA)

The X9SRA motherboard series has ve

fan headers (Fan 1~Fan 4 and Fan A).

These fans are 4-pin fan headers. Pins

1-3 of these fan headers are backward

compatible with the traditional 3-pin fans.

However, the fan speed control setting in

the BIOS Hardware Monitoring section

will only work with 4-pin fans. This allows

the BIOS to automatically set fan speeds

based on the system temperature. Refer to

the table on the right for pin denitions and

fan usage. We recommend that 4-pin fans

are used on the motherboard.
