Fan Headers
There are six fan 4-pin headers. Pins
1-3 are backward compatible with
the traditional 3-pin fans, but you can
use 4-pin fans to take advantage of
the fan speed control using Pulse
Width Modulation through the BMC.
This allows the fan speeds to be
automatically adjusted based on the
motherboard temperature. Refer to
the table on the right for pin definitions.
Chassis Intrusion
A Chassis Intrusion header is located
at JL1 on the motherboard. Attach the
appropriate cable from the chassis
to alert a chassis intrusion when the
chassis is opened.
