Fan Headers
The X9DA7/X9DAi has eight fan
headers, all of which are 4-pin fans.
However, pins 1-3 of the fan headers
are backward compatible with the
traditional 3-pin fans. See the table
on the right for pin defi nitions. The
onboard fan speeds are controlled by
Thermal Management (via Hardware
Monitoring) under the Advanced
Section in the BIOS. The default is
disabled. When using Thermal Man-
agement setting, please use all 3-pin
fans or all 4-pin fans.
