FRACTAL DESIGN Dynamic X2 GP-18 PWM Black

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.
