140MM Basic SERIES The Nexus 140mm Real Silent Case Fan is the ultimate solution to bring some extra airflow in your quiet computer. Don't you just hate it when you have build a nice and quiet computer and it turns out that your high-end components are producing so much heat the temperatures in your computer case are getting too high? The Nexus Real Silent case fan is the solution for you. It provides the extra airflow your pc may require without being noticeable noise wise. Speed The Nexus Real Silent 140mm Case fan has a fan speed of 1000 RPM (+/-10%). The fan speed is fixed at 1000 RPM at 12V. Airflow The airflow of the fan ishuge with 46.87 CFM (78.15m3/hour) you have a lot of air moving at a minimum noise level. Note that for good and efficient cooling the static pressure is also an important value. Be assured that the Nexus fan has very high static pressure so work very effectively. Noise The Nexus 140mm Real Silent case fan produces only 19 dB(A)* measured in a chamber with 15 dB(A) background noise. 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 max 18dB(A). Reading is done using a Spectrum 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.
