Setting Up Your Computer

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:

The operating temperature specifications indicated in this 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" 

• Leave a 10.2 cm (4 in) 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).
