Chassis Enclosure & Ventilation Requirements

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 14 cm (5.5 in.) minimum clearance on all vented sides of the computer which has ODD
configuration to permit the airflow required for proper ventilation. And for computer without ODD
configuration, it needs to leave a 10 cm (3.9 in.) minimum clearance on all vented sides.

Recommended Enclosure

Do not install your computer in an enclosure that does not allow airflow / dusty environment /
temperate over 35 degrees centigrade. Do not put any objects to directly block air-vent. 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, under a desk, or hang on wall by VESA mount,
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.
