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.
