Cooling Shroud; Removing The Cooling Shroud - Dell PowerEdge E31S Series Owner's Manual

Cooling shroud

The cooling shroud aerodynamically directs the airflow across the entire system. The airflow passes through all the critical parts
of the system, where the vacuum pulls air across the entire surface area of the heat sink, thus allowing increased cooling.
