Fan Headers
The X11SDV-8C-TP8F has six 4-pin fan headers (FAN1 ~ FAN4, FANA, FANB). These
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 the IPMI 2.0 interface. Refer to
the table below for pin definitions.
