Fan Headers
There are three 4-pin fan headers (FAN1~FAN3) located on the front plane (see locations
below). These 4-pin fan 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
BMC 2.0 interface. Refer to the table below for pin definitions.
