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
automatically adjusted based on the
motherboard temperature. Refer to
