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 Designed alongside our high-end Venturi Series, the Dynamic X2 incorporates aerodynamic elements of airplane wing designs for significant noise reduction. Available in multiple color combinations including black, white, or the classic Fractal Design color scheme with white blades and black frame, the Dynamic X2 series are the perfect choice for anyone seeking an expertly balanced fan with exceptional dependability. Aerodynamically inspired Aerodynamic stator with embedded wiring helps reduce noise and unwanted turbulence Stator struts sit on a wide angle to the trailing edge of the blades, resulting in a lower noise level and smoother noise profile Strategically placed notches near the fan hub on the trailing edge of the blades help to eliminate the humming noise produced when the blades pass stator struts Trip wire technology introduces a micro-turbulent layer that helps to combat elements that negatively affect performance, providing an overall more efficient and quiet fan environment Focus on longevity High-grade LLS bearing with 100,000-hour MTBF delivers long-lasting dependability Counter-balanced magnet reduces axial tension on the bearing, resulting in less wear over time Specification Type: 14cm Case Fan AMD/Intel: N/A Fan Connector(s): 3-pin Installation: Screws LED Lightin No Colour: White LED Lightin - Weight: 142 g Fan Dimensions: 140 x 140 x 25 mm Fan Controller: No Rotation Speed: 1000 RPM Fan Bearin Long Life Sleeve bearing Air Flow: 68.4 CFM Noise level: 18.9 dB (A) Power: Input power: 1.32 W Max input current: 0.20 A Input voltage: 12 V Starting voltage: 4 V MTBF: \"100,000 hours\" Package Contents: Dynamic X2 Series fan Screw pack with 4 metal fan screws Package Type: Retail Package Weight: 0.1960 kg Warranty: 2 Years
