Headers - Supermicro X11SBA-LN4F/F User Manual

Headers

Fan Headers
There are two 4-pin fan headers on the motherboard. Although pins 1-3 of the fan headers
are backward compatible with the traditional 3-pin fans, we recommend you use 4-pin fans to
take advantage of the fan speed control via Pulse Width Modulation through the BMC. This
allows the fan speeds to be automatically adjusted based on the motherboard temperature.
External Speaker
The JD2 header is for the external speaker. If you wish to use an external speaker, connect
its cable to pins 1-4.
