All new Silent Series R2 Blackout Edition 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 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
