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

Results: Airflow through a nylon filter

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.

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 Elite – The new king of coolers?

I will start this year’s cooler tests with a real treat. I’ve prepared a review of the Dark Rock Elite cooler, the absolute top of BeQuiet!’s range. This is a premium cooler offering very high performance at low noise levels thanks to its sophisticated design in combination with high-end fans. I’m very curious to see how it performs compared to the high-end coolers I’ve had the opportunity to test over the past year. Read more “BeQuiet! Dark Rock Elite – The new king of coolers?” »

BeQuiet! Pure Wings 3 (BL108): Efficient and “cheap” in 140 mm

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. Read more “BeQuiet! Pure Wings 3 (BL108): Efficient and “cheap” in 140 mm” »

12VHPWR cable thermal imaging: Different PSU, different temps

Something for warm-up. We’ll start our ATX 3.0 PSU tests with perhaps the most talked about topic surrounding them, the temperatures of the new cables with 16-pin PCIe connectors. The overview of the PSUs of twelve brands answers well the question of how the manufacturers handled which models. With high current loads, the temperature differences can be quite significant, both on the connector housings and on the wire insulation.
