All new Silent Series R2 fans are equipped with high performance hydraulic bearings, increasing both fan performance and reliability
The 120mm and 140mm fans come with a low-speed adapter, which lets you choose between two different rotation speeds without a separate fan controller
Each fan 60mm and larger is packaged with both 4 metal screws and 4 rubber screws to ensure maximum fan-mounting options
Using the rubber screws allows mechanical decoupling from the case itself, reducing vibrations and decreasing the noise level (40 and 50mm feature metal mounting screws only)
