Onboard Fan Headers
Four 4-pin fan headers (FAN1-FAN4) are located on the motherboard to provide CPU/system
cooling. These fan headers support both 3-pin fans and 4-pin fans; however, onboard fan
speed control is available only when all 4-pin fans are used in your system. Fan speed
control is supported by a thermal management setting in the BMC (Baseboard Management
Controller). See the table below for pin defi nitions.
