Fractal Design Dynamic GP 14 Computer Fan Silent High Airflow 140x140x25 mm 1000RPM FDB Bearings Trip Wire Aerodynamically shaped struts 12v Black Edition (Single)

Hydraulic bearings: Cost-efficient compromise between a standard sleeve bearing and a true FDB bearing Counter-balancing magnet: Reduces the axial tension on the bearing, further protecting the longevity of the bearing Optimized fan geometry: Creating a good balance between static pressure and maximum airflow, resulting in good performance in all usage scenarios Aerodynamically shaped thin stator struts (including wire strut), mimicking the design commonly found on airplane wings: Delivering correct angles allowing for air to easily pass through reducing noise and unwanted turbulence Stator struts are angled perpendicular to the blades: Reduces noise commonly emitted when the blades pass the struts; In effect, minimal noise that may be emitted will be constant and therefore almost inaudible Trip wire technology: Commonly found in airplane wing designs, offering a micro-turbulent layer that helps to combat the elements that negatively affect performance; The presence of the trip wire overall provides a more efficient and quiet fan environment
