Fan Headers
This motherboard has six system/CPU
fan headers (Fan 1~Fan 4, Fan A and
FAN B) on the motherboard. All these
4-pin fans headers are backward com-
patible with the traditional 3-pin fans.
However, fan speed control is available
for 4-pin fans only. The fan speeds are
controlled through IPMI connection.
Chassis Intrusion
A Chassis Intrusion header is located
at JL1 on the motherboard. Attach an
appropriate cable from the chassis to
inform you of a chassis intrusion when
the chassis is opened.
