be quiet! SILENT WINGS 2 140mm computer case Fan

Silent Wings 2, 140 mm, 1000 rpm, 15.8 dB SILENT WINGS 2 140mm
SilentWings 2 fans provide the greatest performance-to-noise ratio and highest reliability on the market. They achieve their virtually silent operation without sacrificing airflow, and so offer the perfect balance between superior cooling and serenity as low as 15.8 dB(A).
Their secret: a unique airflow-optimized fan blade design, custom anti-vibration mounts, and a high-tech fluid dynamic bearing with copper core for greatly reduced noise and super-long life.
SilentWings 2 fans are your best choice for any application that requires ultimately quiet operation and uncompromised performance.

Virtually inaudible
Advanced fluid dynamic bearing (FDB) with high quality oil avoids mechanical friction. Improved modular vibration damping mounts and rubberized frame help prevent transmission of vibration to computer case and its components. Advanced IC motor controller reduces electronic noises.

Super-long life
The FDB’s copper core enables super-long life of up to 300.000h by accelerating heat dissipation.

Superior cooling
Unique airflow-optimized fan blade design maximizes cooling and reduces noise-generating turbulence.

Flexible mounting
Flexible mounting options include screwless installation to case or components as well as mounting with screws.
