Fans
For cooling and airflow, the system contains three removable chassis fans to cool the boards and removable media drives. The integrated power supply fan provides more cooling and airflow.
✏NOTE
The fan has two connectors on its cable. One is labeled “N440BX” and should only be connected a system fan connector on the Intel N440BX Server Board. The other connector is label “ATX” and can be connected to any ATX compliant board.
