Some fans are “too expensive”, others suffer from several technical imperfections. Naturally, these come from being made cheaper, but there is also an attempt to strike a sort of… balance. This, for example, from BeQuiet!, with its Pure Wings models. We compared the latest variants with serial number 3 (Pure Wings 3) in detail with massive competition in 120mm format. And they can be described as the most perfect in history. Undoubtedly.
Results: Static pressure through a plastic filter
Why is there a missing value sometimes? There may be more reasons. Usually it is because the fan could not be adjusted to the target noise level. Some have a higher minimum speed (or the speed is low, but the motor is too noisy) or it is a slower fan that will not reach the higher decibels. But the results in the graphs are also missing if the impeller is brushing against the nylon filter mesh. In that case, we evaluate this combination as incompatible. And zero in the graphs is naturally also in situations where we measure 0.00. This is a common occurrence at extremely low speeds with obstructions or within vibration measurements.
