Onboard Fan Header
This motherboard has seven fan headers (FAN1~6, FANA). All these 4-pin fan headers
are backward-compatible with traditional 3-pin fans. However, onboard fan speed control is
available only when all 4-pin fans are used on the motherboard. Onboard fan speeds are
controlled by thermal management via the BMC (or by IPMI) See the table below for pin
definitions.
