Fan Headers

There are eleven system/CPU fan

headers (Fans 1~6, Fans A~D and Fan

11) on the motherboard. All these 4-pin

fans headers are backward compatible

with traditional 3-pin fans, however, fan

speed control is available for 4-pin fans

only. The fan speeds are controlled

by rmware thermal management via

IPMI. See the table on the right for pin

denitions.

Power LED/Speaker

On JD1 header, pins 1-3 are used for

power LED indication, and pins 4-7 are

for the speaker. 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. See the

tables on the right for pin denitions.
