X7DCL-3/X7DCL-i User's Manual

Fan Headers

The X7DCL-3/X7DCL-i has four chassis/
system fan headers (Fan3 to Fan6), and
two CPU Fans (Fans 1/2). 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 nitions. Note: The onboard
fan speeds are controlled by Thermal Man-
agement via BIOS Hardware Monitoring in
. (
the Advanced Setting
is Disabled.) Please use all 3-pin fans or
all 4-pin fans on the motherboard.

Chassis Intrusion

A Chassis Intrusion header is located at
JL1 on the motherboard. Attach an appro-
priate cable from the chassis to inform you
of a chassis intrusion when the chassis is
opened.
