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 defi 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
