BeQuiet! Pure Wings 2 (BL039): It wouldn’t do without the grooves

Results: Static pressure through a thinner radiator

So, now we get to see what the grooves on the entire surface of the blades, which are typical of BeQuiet! fans, are worth! Judging by the geometry, we were initially concerned that the results might go in a similar direction to the Arctic BioniX F120. But it’s a lot better than that, and the 120 mm Pure Wings 2 even achieves a top price/performance ratio while running very quietly. The best of the fans tested so far.

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! Pure Wings 3 (BL105): Silent, efficient, okay price

Cooling, Extra tests, Fans | | Ľubomír Samák

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.
