Fan Headers
There are six fan headers on the
serverboard, 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 ni-
tions. 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 Ther-
mal Management setting, please use
all 3-pin fans or all 4-pin fans.
