FRACTAL - Fractal Design Dynamic X2 GP-18 PWM 18cm Case Fan, Long Life Sleeve...

 

Super-sized airflow

The Dynamic X2 GP-18 is a powerful 180 mm fan that packs a mean punch in the air-flow department. Massive blades, stout 38 mm thickness, and a wide 300-1200 RPM range with PWM control allow the GP-18 to yield remarkably high airflow while remaining exceptionally quiet.
 
Massive 180 x 38 mm fan that yields remarkably high airflow while remaining very quiet
High-grade LLS bearing with 90,000-hour MTTF delivers long-lasting dependability
PWM support offers a wide 300-1200 RPM speed range for silent operation under lighter loads and maximum airflow during more demanding activity
Optimized fan geometry balances airflow with extra emphasis on static pressure for great performance in any usage scenario
Aerodynamic stator struts with embedded wiring helps reduce noise and 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 quieter fan environment
Customized design contributes to a cool running and beautiful looking build
Fits standard 180 mm fan mounts with 165 x 165 mm screw hole pattern
