Fan Headers
This motherboard has
ers (Fan1-Fan10) on the motherboard. These
4-pin fan headers are backward compatible with
the traditional 3-pin fans. However, fan speed
control is available for 4-pin fans only by thermal
management via IPMI 2.0 interface. See the table
on the right for pin definitions.

A System Management Bus header for IPMI 2.0
