These fans have been specifically developed to deliver significant airflow while maintaining low noise levels. Silent Series R2 fans are available in sizes from 40mm up to 140mm.
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).
