4.2 Headers and Connectors
Fan Header
There are four 4-pin fan headers (FAN1–FAN3, FANA) on the motherboard.
They are
backward compatible with a traditional 3-pin fan. Four-pin fan speed is controlled by Thermal
Management (via Hardware Monitoring) in the IPMI 2.0. Use all 4-pin fans on the motherboard
for better thermal management and system cooling.
