Noctua NF-A4x20 PWM - 40mm x 20mm 5000RPM Cooling Fan

Featuring advanced aerodynamic design measures such as flow acceleration channels and Noctua's AAO frame, the NF-A4x20 is a highly optimized, premium-quality quiet fan.

Key Selling Points

Flow acceleration channels
AAO frame

Product Features

The NF-A4x20 impeller features suction side flow acceleration channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.

Noctua's AAO frames feature integrated anti-vibration pads as well as Noctua's proprietary stepped inlet design and inner surface microstructures, both of which further refine the fan's performance/noise efficiency.
