Cooling Shroud
Removing the Cooling Shroud
CAUTION: The computer will be populated with one or two CPUs. Currently, when there is a single CPU installed,
airflow can bypass CPU1 which increases fan speeds and therefore leads to poor acoustic performance. Adding a
mylar piece in this region redirects airflow across CPU1. The mylar piece will need to be removed when the 2nd
CPU is installed as it is no longer needed and will interfere with the heat sink.
