Fractal Design Dynamic GP-14 White Case Fan FD-FAN-DYN-GP14-WT Featuring hydraulic bearings; a cost-efficient compromise between a standard sleeve bearing and a true FDB bearing Equipped with a counter-balancing magnet in the hub that reduces the axial tension on the bearing, further protecting the longevity of the bearing Optimized fan geometry for 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, helping to reduce noise commonly emitted when the blades pass the struts. In effect, minimal noise that may be emitted will be constant and therefore almost inaudible to the ear. Available in 140mm fan sizes
