Fan Headers
The X11SDW-16C-TP13F 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.
This motherboard supports dual cooling zone. The table below specifies which fan belongs
in which zone. Refer to the table below for pin definitions.
