Setting Up and Using Your Computer
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 your Owner’s Manual reflect the maximum
ambient operating temperature. The room’s 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 163.
• Leave a 10.2 centimeter (4 inch) 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% airflow through the
enclosure (front and back).
