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 manual reflect the maximum ambient operating temperature. The ambient room 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 167. • 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.
