3.2 Headers and Connectors
Onboard Fan Header
This motherboard has six fan headers (FAN1~FAN4, FANA, FANB) used for CPU/system
cooling. These are all 4-pin fan headers, which are backward compatible with a traditional
3-pin fan. The onboard fan speed is controlled by Thermal Management via the IPMI 2.0
interface. The motherboard supports dual cooling zones. The table below shows which fan
belongs to which zone.
