If your enclosure has doors, they need to be of a type
that allows at least 30% airow through the enclosure
(front and back).

all vented sides of the computer to permit the
airow required for proper ventilation.

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.

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 airow required for
proper ventilation.
