IBM PC 300GL manual PC300 PL and GL tower, Heat output, Airflow, Acoustical noise-emission values

Page 29

Note: Power consumption and heat output vary depending on the number and type of optional features installed and the power-management optional features in use.

Heat output

•Approximate heat output in British thermal units (Btu) per hour:

—Minimum configuration: 256 Btu/hr (75 watts)

—Maximum configuration: 706 Btu/hr (207 watts)

Airflow

•Approximately 0.5 cubic meter per minute (18 cubic feet per minute)

Acoustical noise-emission values

•Average sound-pressure levels:

—At operator position:

–Idle: 33 dBA

–Operating: 39 dBA

—At bystander position-1 meter (3.3 ft):

–Idle: 4.4 bels

–Operating: 4.9 bels

Note: These levels were measures 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.
