Fractal Design R2 FD-FAN-SSR2-140 Silent Series 140mm Case Fan 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) • Mfr Part Number: FD-FAN-SSR2-140 • Low Speed: Speed: 850 +/- 200 RPM Starting Voltage: <11 Max.
