Product Overview Aerodynamic Technology, Cool Design The Fractal Design Dynamic X2 series are true all-purpose fans, offering excellent airflow & outstanding 100, 000-hour life expectancy thanks to the new LLS (Long Life Sleeve) bearing. Added PWM support offers precise fan control via a wide speed adjustment range allowing users to select their ideal mix of silent operation & maximum airflow. The customized design of the Dynamic X2 results in a beautiful fan that helps to keep your system cool, yet quiet. Designed together with Fractal Design's high-end Venturi Series, the Dynamic X2 incorporates aerodynamic elements of airplane wing designs for significant noise reduction. Available in multiple colours including black, white, & the classic Fractal Design white-on-black combination, the Dynamic X2 series are the perfect choice for those seeking an expertly balanced fan with exceptional dependability. Features• High-grade LLS bearing with 100, 000-hour MTBF delivers long-lasting dependability. • PWM support offers a wide 500 to 2, 000 RPM speed adjustment range for silent operation under lighter loads & maximum airflow during more demanding activity. • Counter-balanced magnet reduces axial tension on the bearing, resulting in less wear over time. • Optimized fan geometry balances airflow with extra emphasis on static pressure for great performance in any usage scenario. • Aerodynamic stator with embedded wiring helps reduce noise & unwanted turbulence. • Stator struts sit on a wide angle to the trailing edge of the blades, resulting in a lower noise level & 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 & quiet fan environment. • Customized design contributes to a cool running & beautiful looking build. • Available in 120mm & 140mm sizes & multiple colours including black, white or the signature Fractal Design white-on-black combination.
