Fan Headers
This motherboard has six system/
CPU fan headers (Fan 1~Fan 4, Fan
A, Fan B) 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 Thermal
Management via Hardware Monitoring
in the Advanced Setting in the BIOS.
(See Chapter 5 for more details.) See
the table on the right for pin de
fi nitions.
Power LED/Speaker
On JD1 header, pins 1-3 are used for
power LED indication, and pins 4-7 are
for the speaker. See the tables on the
right for pin de
fi nitions. Please note
that the speaker connector pins (4-7)
are used with an external speaker. If
you wish to use the onboard speaker,
you should close pins 6-7 with a
jumper.
