Hush ......

I have long wondered whether I should opt for this fan. Because I wanted to have no less than five of them and I needed 3x140mm and 2x120mm. Since I did not want different in my new fan housing. As I said've read a lot and compare because it's quite a sum of money ("only" for fans). But I was not disappointed. The installation is really great and they are really quiet. I am glad that finally I have decided the same for these fans. So I went a potential double sale out of the way. So strong buy recommendation from me. They are worth the money in any case. One hears the most drafts but not the fans.
