ATX Thermal/Mechanical Design Information

Thermal and Mechanical Design Guidelines

6.2.2

Acoustics

To optimize acoustic emission by the fan heatsink assembly, the reference design

implements a variable speed fan. A variable speed fan allows higher thermal

performance at higher fan inlet temperatures (T

) and lower thermal performance with

improved acoustics at lower fan inlet temperatures. The required fan speed necessary

to meet thermal specifications can be controlled by the fan inlet temperature and

should comply with requirements listed in the following table.

NOTES:

Acoustic performance is defined in terms of measured sound power (LwA) as defined in

ISO 9296 standard, and measured according to ISO 7779.

While the fan hub thermistor helps optimize acoustics at high processor workloads by

adapting the maximum fan speed to support the processor thermal profile, additional

acoustic improvements can be achieved at lower processor workload by using the
