Fractal Design Venturi HP 14 White PWM Computer Fan Silent High Airflow Long Life Time FDB Bearings Aerodynamically shaped struts 12v 140 mm (Single)

True FDB-bearings: providing silent operation coupled with a long lifespan PWM control with a very wide speed range, starting at only 400RPM (400 +/- 100 RPM): Ideal for CPU heatsinks or radiators, where the motherboard can control the fan speed based on the CPU temperature. Counter-balanced magnet: Reduces axial tension on the bearing, resulting in less wear over time Optimized fan geometry for high pressure: Delivering high performance results in high restriction usage scenarios, such as in use with large dense heatsinks or water cooling radiators Aerodynamically shaped thin stator struts: Reduces noise and unwanted turbulence 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
