BeQuiet! Light Wings (140 mm): Different size, different geometry

Results: Airlow w/o obstacles

We analyzed the “Light Wings” fan fairly recently, but that was in the 120 mm format. BeQuiet! approached the 140mm model a little differently. Although the frame is only proportionally enlarged, the shape of the rotor is already significantly different. It relies on long, curved blades, which look great in this cross-section, but there are some design caveats. Still, in some applications, this fan excels.

Results: Airlow w/o obstacles








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.

BeQuiet! Dark Rock Pro 5 – A suitable successor to a legend

BeQuiet!, which I don’t need to introduce here, launched its top-end Dark Rock Elite cooler early this year. Along with it, the Dark Rock Pro 5 was also released, but it has remained somewhat in the shadow of its elite sibling, which I would like to correct today. I firmly believe that the fifth gen of the Dark Rock Pro will successfully build on the previous versions, which have always been known for their uncompromising cooling performance and quiet operation.

More and faster blades, BeQuiet! Pure Wings 3 (BL113)

Go for the variant with nine longer blades or seven shorter blades? That’s the question we’ll tackle in this test of the Pure Wings 3 140mm fan. In addition to the different geometries, you can also choose between different speed ranges with differently placed maximums. The high-speed variant has the upper hand, as expected, when it comes to needing to achieve the highest possible airflow. But it also excels in other situations.

BeQuiet! Silent Wings 4 (BL117): A white choice for your case

The Silent Wings (Pro) 4 represent the pinnacle of computer fan range. The non-Pro variants stand out especially in system positions and are not well suited for radiators. This is by design and in line with the sort of “micro-segmentation” of BeQuiet. In a white design, like the one tested, it will be quite difficult to find other 140 mm fans that are quieter at comparable airflow. Read more “BeQuiet! Silent Wings 4 (BL117): A white choice for your case” »
