Special Features

• 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
