Fan Headers
This motherboard has four system cooling fan
headers (Fan1-Fan4). All these 4-pin fans headers
are backward compatible with the traditional 3-pin
fans. However, fan speed control is available for
4-pin fans only and is controlled by thermal man-
agement via IPMI 2.0 interface. See the table on
the right for pin definitions.
