Unique airflow-optimized fan blade design reduces noise-generating fan turbulence
Advanced fluid dynamic bearing providing for greatly reduced operating noise
Improved modular vibration damping mounts and rubberized frame help prevent transmission of vibration to computer case and its components
Advanced high quality IC motor controller reduces electrical noise
Advanced fluid dynamic bearing (FDB) with industrial grade lubricant eliminates direct contact between rotor and 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 and result in maximum operating silence
The SilentWings 2 fan family provides the greatest airflow-to-noise ratio and highest reliability on the market. Key to these fans' unrivaled and uncompromising performance are a unique airflow-optimized fan blade design, custom anti-vibration mounts, and a high-tech fluid dynamic bearing with copper core that greatly reduces noise and imparts super-long life. Through this advanced technology these fans achieve virtually silent operation without sacrificing airflow, and so offer the perfect balance between superior cooling and serenity.The member of the family, SilentWings 2 PWM, adds variable-speed capability to this formidable combination of features and abilities. Just connect one to the PWM header on your mainboard or fan controller to achieve fine control over the fan speed and noise profile.
