Fan Headers
The serverboard has twelve fan headers.
Fans 1~4 are for CPU/system use and
Fans A~H for GPU use.. All are 4-pin fan
headers, which are backward compatible
with traditional 3-pin fans. However,
fan speed control is available for 4-pin
fans only. The fan speeds are controlled
by Thermal Management via IPMI 2.0
interface. See the table on the right for pin
definitions.
