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.
NOTE: Systems that support the internal hard drive tray require low-profile heat sinks and do not
require or support a cooling shroud.
