An automated fan test plenum, developed and produced by ViAcoustics, provides the capability of characterizing the performance and sound emission of small cooling fans that are being considered for use in space flight hardware or similarly-sized information technology equipment or other commercial products.

The operation of the fan test plenum is documented in the following publications:
