Heat Output
Ÿ
Approximate heat output in British thermal units (Btu) per hour:
– Maximum configuration (as shipped): 361 Btu/hour (106 watts)
– Maximum configuration (theoretical):
3
1564 Btu/hour (460 watts)
Air flow
Ÿ
Approximately 0.56 cubic meters per minute (20 cubic feet per minute)
Acoustical Noise-Emission Values
Ÿ
Average sound-pressure levels:
– At operator position:
- 40 dBA idle
- 44 dBA operating
– At bystander position–1 meter (3.3 ft):
- 37 dBA idle
- 40 dBA operating
Ÿ
Declared (upper limit) sound power levels:
– 5.2 bels idle
– 5.5 bels operating
Note: These levels were measured in controlled acoustical environments
according to 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 your
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.
3 Under typical maximum configurations, the heat output will be substantially below
the theoretical maximum.
