Fan Headers

The X7DB8-X/X7DBE-X has six chassis/sys-
tem fan headers (Fan1 to Fan6) and two CPU
Fans (Fans 7/8). (*Note: Fan1 to Fan4 are
3-pin fans, and Fan5 to Fan8 are 4-pin fans.
However, Pins 1-3 of 4-pin fan headers are
backward compatible with the traditional 3-pin
fans.) See the table on the right for pin defi ni-
tions. (*The onboard fan speeds are controlled
by Thermal Management via BIOS Hardware
Monitor in the Advanced Setting
Disabled.)

Keylock

The keyboard lock connection is designated
JK1. Utilizing this header allows you to inhibit
any actions made on the keyboard, effectively
"locking" it.
