Fan modules cool the chassis by circulating air through the enclosure. The rate at which air moves (the airflow) determines the amount of cooling. This airflow is a function of fan speed (rpm).

Fan modules cool the chassis by circulating air through the enclosure. The rate at which air moves (the
air
ow) determines the amount of cooling. This air
ow is a function of fan speed (rpm). These fans
can operate at multiple speeds. This ensures that when the enclosure temperature changes, the fans
can automatically adjust the air
ow. If one fan operates too slowly or completely shuts off, the other
fan operates at a higher speed. At the same time, the error condition is reported to the user via the
LCD panel on the front of the controller.
