Fan Headers
The X11SDV-16C/-12C/-8C-TP8F has six 4-pin fan headers (FAN1 ~ FAN4, FANA, FANB).
These headers are backwards-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.
