Fan Headers
The X10SRA motherboard has five fan
headers (Fan1 ~ Fan5). These fans
have 4-pin fan headers. Pins 1-3 of
the fan headers are backward com-
patible with the traditional 3-pin fans.
However, the fan speed control set-
ting 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 definitions and fan usage.
We recommend that 4-pin fans are
used on the motherboard.
Speaker
On the JD1 header, Pins 6~7 are used
for internal/external speaker. Close
pins 6~7 with a cap to use the onboard
speaker. If you wish to use an external
speaker, attach the external speaker
cable to pins 6~7 instead. See the
table on the right for pin definitions.
