Fan Headers
This motherboard has four system/CPU/
fan headers (Fan 1-Fan 3, Fan A) on
the motherboard. All these 4-pin fans
headers are backward compatible with
the traditional 3-pin fans. The fan speeds
are controlled via firmware management
via IPMI interface. See the table on the
right for pin definitions.
