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.
Removing the cooling shroud

CAUTION: Many repairs may only be done by a certified service technician. You should only perform
