Installing Your Computer in an Enclosure
Installing your computer in an enclosure can restrict the airflow and impact
your computer’s performance, possibly causing it to overheat. Follow the
guidelines below when installing your computer in an enclosure:
NOTICE: The operating temperature specifications indicated in this Owner’s
Manual reflects the maximum ambient operating temperature. The room ambient
temperature needs to be a consideration when installing your computer in an
enclosure. For example, if the ambient room temperature is at 25° C (77° F),
depending on your computer’s specifications, you only have 5° to 10° C (9° to 18° F)
temperature margin before you reach your computer’s maximum operating
temperature. For details about your computer’s specifications, see "Specifications"
on page 177.
Leave a 10.2 cm (4 inches) minimum clearance on all vented sides of the
computer to permit the airflow required for proper ventilation.
If your enclosure has doors, they need to be of a type that allows at least
30 percent airflow through the enclosure (front and back).
If your computer is installed in a corner on a desk or under a desk, leave at
least 5.1 cm (2 inches) clearance from the back of the computer to the wall
to permit the airflow required for proper ventilation.
