Cooling fan noise usually manifests itself late in a product’s development, derailing progress and requiring improvised “fixes” that are seldom successful. The reasons this occurs remain mysterious to most of the engineering community, which continues to hunt for the largely mythical “quiet fan” that solves all problems. A far better approach is to be aware of the design factors that determine noise emission near thje outset of the project. These include cooling requirements, thermal design practices, flow path resistance, form factor and dimensional constraints, upstream turbulence, and of course fan selection. While some fans are indeed much quieter than others, no fan can guarantee a quiet outcome when used in a noisy system.
This half-day workshop introduces an integrated approach applying fan similarity laws, vendor data, and empirical models that lead to noise emission estimates. These can then be used to assess the impact of various design choices. This approach leads to actionable insight that supports making and justifying wise design decisions at an early date using readily-available design parameters and simple math.
Examples will be drawn from the instructor’s consulting experience in IT, consumer products, commercial equipment, and aerospace. No prior experience in acoustics is required. Audio demonstrations are used to illustrate key points. Instruction involves mathematics no more advanced than logarithms. Each registrant will receive a bound copy of the course slides.
