There are eight fan headers on the
serverboard, all of which are 4-pin
fans. However, pins 1-3 of the fan
headers are backward compatible

controlled by Thermal Management

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.
