Be Quiet Shadow Wings SW1 120mm High-Speed Case Fan The Silent Wings 2 fan family provides the greatest airflow-to-noise ratio & highest reliability on the market. Key to these fans’ unrivalled & uncompromising performance are a unique airflow-optimized fan blade design, custom anti-vibration mounts, & a high-tech fluid dynamic bearing with copper core that greatly reduces noise & imparts super-long life. Through this advanced technology these fans achieve virtually silent operation without sacrificing airflow, & so offer the perfect balance between superior cooling & serenity. The newest member of the family, Silent Wings 2 PWM, adds variable-speed capability to this formidable combination of features & abilities. Just connect one to the PWM header on your mainboard or fan controller to achieve fine control over the fan speed & noise profile. The Silent Wings 2 PWM 140mm model is the largest fan we make that combines all of the above class-leading features. It provides maximum cooling airflow & operating noise levels down to a virtually silent 16.4 d B (A). Feature Details Virtually Silent Operation Silent Wings 2 fans include a wide array of electronic & mechanical optimizations for superior air flow with very low noise production Unique airflow-optimized fan blade design reduces noise-generating fan turbulence Advanced fluid dynamic bearing providing for greatly reduced operating noise enhanced modular vibration damping mounts & rubberized frame help prevent transmission of vibration to computer case & its components Option for direct hard mount when preferred Advanced high quality IC motor controller reduces electrical noise Variable Speed Function Pulse Width Modulation (PWM) allows compatible 4-pin controllers (including those built into many motherboards) to intelligently vary the speed (and thus the noise level) of the fan. With PWM your system can ramp up the cooling when it’s needed, or operate in maximum quiet mode when it’s not. Engineering Advanced fluid dynamic bearing (FDB) with industrial grade lubricant eliminates direct contact between rotor & frame, resulting in extremely low noise levels The FDB has a copper core that conducts heat away from the bearing more effectively, enabling super-long fan life of up to 300, 000 hours Dynamically balanced fan blades enhance reliability & result in maximum operating silence German product conception, design & quality control Outstanding Service & Support 3 year manufacturer's warranty General Specs
