The workmanship is very good and an absolute good optics. For tidy housing and casemoding. As you might expect from Corsair, which was my reason to buy! The LED will light mainly only the leaves and lit bask not much. What's the big drawback is the volume. From 600-700 hundred revolutions the min. they clearly heard from the case out and everything wetere addition is then only unbearably loud and annoying! Why has the name of quiet not deserve for me!
I've often read that they do not listen or are silent in advance. For this I can only say that my standard LED fan from Zalman Z11 Plus from the housing, the same voltage are always a lot quieter !! Who really silent fan looking should look elsewhere! I have reasons of appearance and adds to reserve now. Although I in the UEFI speed have significantly runtergeschraubt
