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

Cooling shroud

The cooling shroud has aerodynamically placed openings that direct 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.
