Acoustical noise emissions:

• Sound power, idling: 5.0 bels
• Sound power, operating: 5.3 bels

1. Power consumption and heat output vary depending on the number
   and type of optional features installed and the power-management optional
   features in use.
2. These levels were measured in controlled acoustical environments
   according to the procedures specified by the American National Standards
   Institute (ANSI) S12.10 and ISO 7779 and are reported in accordance
   with ISO 9296. Actual sound-pressure levels in a given location might
   exceed the average values stated because of room reflections and other
   nearby noise sources. The declared sound-power levels indicate an
   upper limit, below which a large number of computers will operate.
