Fan Headers
The X7DCA-3/X7DCA-i has fi ve chassis/
system fan headers (Fans 1~Fan 6), and
two CPU Fans (Fans 7~8). All these fans
are 4-pin fans. These 4-pin headers also
support 3-pin fans. See the table on the right
for pin defi nitions.
Note: The onboard fan speeds are
controlled by Thermal Management
via BIOS Hardware Monitoring in the
Advanced Setting. (The default setting
is Disabled.)
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.
