We have compared this case fan with the quietest case fans available and we simply cannot find another one this quiet! Noise Testing When we test the noise level of our case fans we do this in an anechoic test chamber under free air condition. The chamber used for testing this fan background noise is 15dB(A). Reading is done using a Spectrun Analyzer. Nexus provides the exact details of our noise level test as we feel dB(A) values are difficult values to compare as there are many ways of testing and calculating. In the market there are a lot of unrealistic dB(A) value-claims which are often calculated by means of extrapolation. This in fact does not give a realist view of the fans noise level performance.
