Fan Headers

The X7DB8/X7DBE has eight chassis/system
fan headers (Fan1 to Fan8) and two CPU Fans
(Fans 7/8). (Note: all these fans are 4-pin fans.
However, Pins 1-3 of the 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, When using Thermal Management
setting, please use all 3-pin fans or all 4-pin
fans on the motherboard.)

Keylock

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