Fan Headers

The X7DBU/X7DGU has eight chassis/system

fan headers (Fan1 to Fan8.) Fan1-Fan6 are

chassis/system fans, while Fan7 and Fan8 are

CPU fans. Fan5-Fan8 are 4-pin fan headers.

Pins 1-3 of the 4-pin fan headers are backward

compatible with the traditional 3-pin fans. The

fan speeds for the 4-pin fans are controlled

by Thermal Management via BIOS Hardware

Monitor in the Advanced Setting. The default

setting is Disabled. See the table on the right

for pin de nitions. (*Note: all these fans are

4-pin fan connectors. However, Pins 1-3 of

the fan headers are backward compatible with

the traditional 3-pin fans.)

The keyboard lock connection is designated

JK1. Utilizing this header allows you to inhibit

any actions made on the keyboard, effectively

"locking" it.
