Onboard Fan Header
Eight 4-pin fan headers (FAN1~6, FANA, FANB) 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 the motherboard.
Fan speed control is supported by a thermal management setting in the BMC (Baseboard
Management Controller). See the table below for pin defi nitions.
