The long break is over, back to fans. BeQuiet! recently updated its entry-level line – Pure Wings – and at least the slower 140-millimeter models have to be on your radar. The Pure Wings 3 fans in the BL108 variant represent an extremely efficient low-cost option for some situations, while not suffering from the common shortcomings of their price class. What’s quiet here is not only the aerodynamic component, but also the motor one.
Results: Static pressure through a hexagonal grille
Note: “Higher is better” (the result of static pressure in the charts) is only valid for comparing fans of the same formats. We have discussed what the quantity “static pressure” means and how to understand it in this article.
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.
Yay, I have been starving for HWcooling fan reviews for a while now.
The links are broken in the last page. It’s spelled bl-108 in the last page but the url of the article itself is spelled bl108.
Fixed. Thanks! 🙂
Thanks for that enormous quantity of information, now, being compared the Pure Wings 2 140mm vs Pure Wings 3 140mm which would be best ? and it would be reasonable to replace PW2 with PW3 ?
We have not tested the older Pure Wings (2) fan in 140 mm format. Some correlations and better estimates can be made after the results of the 120 mm PW3 are completed (there will be a comparison with the 120 mm PW2). Although, of course, it will not be completely accurate. With the size of the blades the character of the noise and the colour of the sound changes. And also across formats it is not just a matter of making the impeller in the 1.00:1.16 scale ratio.
Well, the results of the 140-millimeter Pure Wings 2 might be added eventually, but it’s not a big priority.
