My first contact with these nice parts was of a computer from the electrical scrap. After these times have then taken a closer look at me and had also built on fan in functional PC's, I quickly realized the benefits that they bring with them. Very loud fans are a bit quieter. The vibrations are no longer forwarded directly to the housing, but very well swallowed by rubber. Next they accelerate the entry and expansion of individual fan when faulty. OK, the expansion requires a bit fiddly job, but ... for screwless case, you also the fan can now install without screws)
What do these miracles parts but can not, is to make fan completely silent ^^ These still include the right fan, you also get from Xilence ^^ My recommendation for the fans: Xilence - 80mm case fan - Transparent with blue LED and Xilence - 2x 120mm case fan - Transparent with blue LED
