Fan Headers
This motherboard has twelve fan headers
on the motherboard. Fans 1~4 are for
CPU/system use and Fans A~H for GPU
use. All these 4-pin fans headers are
backward compatible with the traditional
3-pin fans. However, fan speed control
is only available for 4-pin fans via IPMI
thermal management. See the table on
the right for pin definitions.
