We had already tested the smaller siblings of the Light Wings in 120 mm and found them to be good. So now comes the test of the be quiet! Light Wings 140 mm PWM and PWM High Speed and it will be interesting to see if they have managed to scale the successful concept in size. Often enough such projects are crowned with success, but now and then the whole thing turns out less optimal. That is exactly what we want to find out today. And the same applies as with the 120 mm fans: Individually or in a three-pack with a hub as a free accessory?
