Fan Headers
This motherboard has eight cooling fan headers (FAN 1 ~ FAN 8) for system cooling.
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 via IPMI 2.0 interface.
See the table below for pin definitions.
