Fan Headers
The X8DTU/X8DTU-F has six chassis/system
fan headers (Fan1 to Fan6) and two CPU fans
(Fan7/Fan8) on the motherboard. All these
4-pin fans headers are backward compatible
with the traditional 3-pin fans. However, fan
speed control is available for 4-pin fans only.
The fan speeds are controlled by a Hardware
Monitoring setting in the BIOS. (The Default
setting is Disabled.) See the table on the right
for pin defi nitions.

Speaker/Power LED Header
On the JD1 header, pins 1-3 are used for
power LED indication, and pins 4-7 are for
the speaker. See the table on the right for
speaker pin defi nitions. Please note that the
speaker connector pins (4-7) are for use with
an external speaker. If you wish to use the
onboard speaker, you should close pins 6-7
with a jumper.
