NCLOSURE & VENTILATION REQUIREMENTS
En
closure Ventilation
If y
our 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.
Rec
ommended Enclosure
Do
not install your computer in an enclosure that does not allow airflow.
This restricts the airflow and impacts your computer’s performance,
po
ssibly causing it to overheat.
Open Desk Minimum Clearance
If y
our 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.
