got myself the Alpenföhn Brocken as CPU fan ... since the Alpenföhn fan is not on this list. The discreet purple (the almost blacklight moderately lit) is a real eye-catcher is ... everyone who has ever seen in my Pc in the dark, is blown away by the purple LED's ... so gets the chunk also a second this great fan so that the purple still a bit more coming through. Personally, I find that all the transparent fan with blue LEDs light up much too exaggerated and cheap ... therefore already really disturbing for me was it while enjoying a movie on PC.
So who no disco in the housing consumption ... which will have its pure joy with this fan ... I like him seh me every time again.
And also the fan is really quiet ... the fans of the case can be heard on the other hand ^^ which are also cursed softly all together.
