Fan Headers
There are three 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 auto-
matically adjusted based on the moth-
erboard temperature. Refer to the
table on the right for pin definitions.
Chassis Intrusion
A Chassis Intrusion header is located
at JL1 on the motherboard (not
