Fractal Design Flexes Silent Series R2 Computer Case Fans
Fractal Design is making a big deal about the use of high performance hydraulic bearings in the Silent Series R2. In addition, each fan 60mm and larger is packaged with both 4 metal screws and 4 rubber screws, the latter of which helps reduce case vibration.
Some fans (60mm and larger) in the Silent Series R2 line come with optional rubber screws that decouple the fans from the case to reduce vibration and cut back on noise.
Fan sizes 120mm to 140mm also come with an adapter to lower the speed, and all Silent Series R2 fans ship with fully sleeved cables to make cable routing easier.
No word on when these will be available or for how much. In the meantime, you can view detailed specs of each fan in the Silent Series R2 line in this PDF document.
