Fractal Design Dynamic X2 GP-14 140mm Case Fan, Long Life Sleeve Bearing, Counter-balanced Magnet, 1000 RPM, Black

A true all-purpose fan, offering excellent airflow and outstanding 100,000-hour life expectancy thanks to its LLS (Long Life Sleeve) bearing
 

• High grade LLS bearing with class leading 100,000 hours MTBF.
• Equipped with a counter-pull magnet that reduces the axial tension on the bearing
• Fan geometry optimized for a good balance between static pressure and maximum airflow, resulting in good performance in all usage scenarios
• Aerodynamically shaped stator struts including the wire strut. Helps reduce noise and unwanted turbulence.
• Stator struts sit on a wide angle to the trailing edge of the blades which result in a lower noise level and smoother noise profile
• Strategically placed notches near the fan hub on the trailing edge of the blades further reducing the humming noise produced when the blades pass the stator struts
• A "trip wire" on the rear side of the blades near the leading edge. The trip wire introduces a larger turbulent boundary layer at an earlier stage, this delays the layer separation and improves both airflow and noise characteristics.
• The customized design of the Dynamic Series fans contributes to a beautiful, cool build
