NZXT Quiet Airflow Fans offer high-performance, low-noise cooling for heat-prone PCs. Optimized blades and a chamfered frame provide powerful concentrated air, while fluid dynamic bearings and PWM control keep things quiet and efficient. Nine sickle-style blades are optimized to move large amounts of air, ensuring versatile use for intake or exhaust. Minimal gap between blade edges and frame maximizes the spinning area for higher airflow and reduced turbulence. Chamfered frame design directs air in a powerful concentrated flow pattern, traveling far into the case to cool vital components. Fluid dynamic bearings provide unwavering stability, low-noise operation, and a 60,000-hour lifespan. PWM control dynamically adjusts fan speed for higher output or lower noise based on system temperatures for efficient cooling. Sturdy frame with rubberized corners absorbs vibrations for low-noise operation, even at high speeds.
