Onboard Fan Header
This motherboard has six fan headers (FAN1~6,). 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. Fan speed control is supported by Thermal
Management via IPMI 2.0 interface. See the table below for pin definitions.
