Results: Frequency response of sound with a radiator
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: Frequency response of sound with a radiator
Measurements are performed in the TrueRTA application, which records sound in a range of 240 frequencies in the recorded range of 20–20,000 Hz. For the possibility of comparison across articles, we export the dominant frequency from the low (20–200 Hz), medium (201–2,000 Hz) and high (2,001–20,000 Hz) range to standard bar graphs.
However, for an even more detailed analysis of the sound expression, it is important to perceive the overall shape of the graph and the intensity of all frequencies/tones. If you don’t understand something in the graphs or tables below, you’ll find the answers to all your questions in this article. It explains how to read the measured data below correctly.
The vast majority of fan sound operates in the 70–7000 Hz band. You can virtually ignore frequencies above 7000 Hz, they reflect electromagnetic noise from the measurement chain. This (electromagnetic noise) also extends to frequencies below 70 Hz, although there is still aerodynamic noise at these frequencies. These bands (below 70 Hz and above 7 kHz) could be safely “cut out”, but we do not. Just in case one of the fans does have an anomaly that needs to be controlled and visualized.
Note: For these measurements a thinner radiator of 28 mm is used. Such thickness (and restrictiveness with FPI 22) is common in practice (also within AIO coolers).

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.
