Fan Headers (FAN1~4, FANA)

The X9SCi-LN4/X9SCA series has five fan
headers (Fan 1~Fan 4 and Fan A). These fans
are 4-pin fan headers. However, Pins 1-3 of the
fan headers are backward compatible with the
traditional 3-pin fans. A fan speed control setting
in the BIOS Hardware Monitoring section allows
the BIOS to automatically set fan speeds based
on the system temperature. Refer to the table
on the right for pin definitions.
Note: Please use all 3-pin fans or all
4-pin fans on a motherboard. Please
do not use 3-pin fans and 4-pin fans
on the same board.

Chassis Intrusion (JL1)

A Chassis Intrusion header is located at JL1 on
the motherboard. Attach the appropriate cable
from the chassis to inform you of a chassis intru-
sion when the chassis is opened.
