ENCLOSURE VENTILATION
If your enclosure has doors, they need to be of a type that allows at least 30% airflow through the
enclosure (front and back).
ENCLOSURE MINIMUM CLEARANCE
Leave a 10.2 cm (4 in.) minimum clearance on all vented sides of the computer to permit the airflow
required for proper ventilation.
RECOMMENDED ENCLOSURE
Do not install your computer in an enclosure that does not allow airflow. This restricts the airflow
and impacts your computer's performance, possibly causing it to overheat.
OPEN DESK MINIMUM CLEARANCE
If your computer is installed in a corner, on a desk, or under a desk, leave at least 5.1 cm (2 in.) clearance
from the back of the computer to the wall to permit the airflow required for proper ventilation.
