Escape from darkness – BeQuiet! Light Wings White (BL101)

Overview of manufacturer specifications

There are only a few white fans with ARGB. Still, BeQuiet’s Light Wings models have some rather unique features as this rare commodity. That’s true visually as well. But they also have high performance or airflow to noise ratio. For our tests this time, out of the two options, we chose the high-speed design, which has its “own” blade geometry. But it also handles very low speeds to boot.

* When reading performance values, a certain amount of tolerance must always be taken into account. For maximum speeds, ±10 % is usually quoted, minimum speeds can vary considerably more from piece to piece, sometimes manufacturers will overlap by as much as ±50 %. This must then also be adequately taken into account for air flow, static pressure and noise levels. If only one value is given in a table entry, this means that it always refers to the situation at maximum speed, which is achieved at 12 V or 100 % PWM intensity. The manufacturer does not disclose the lower limit of the performance specifications in its materials in that case. The price in the last column is always approximate.
** Price calculated per unit, but the fan is not sold separately. It is only available as part of a triple-pack that also includes an ARGB hub.
