The hunch that BeQuiet! couldn’t be this wrong was correct after all and now we have to tuck our tails between our legs. The original headline still stands, so “Don’t swap corners on Silent Wings (Pro) 4! You’d get worse results”, but it’s a little different than how we originally presented it. There has in fact been a mix-up of corners and now we’ll settle everything. We apologize to you, our readers, and to BeQuiet! for the original interpretation.
Results: Airflow through a thinner radiator
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 rotor 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.
