Fan Headers
This motherboard has six system/CPU
fan headers (Fan 1~Fan 5, Fan A1) on
the motherboard. All these 4-pin fans
headers are backward compatible with
the traditional 3-pin fans. However, fan
speed control is available for 4-pin fans
only. The fan speeds are controlled by
rmware thermal management via IPMI
interface. See the table on the right for
pin denitions.
