Massive Airflow and Whisper-Quiet Operation:

Large 200mm Size for High Airflow:

The Noctua NF-A20 PWM features a large 200mm size, allowing it to move a significant volume of air (146.9 m³/h) at lower rotational speeds. This makes it highly effective for cooling large PC cases and components, ensuring optimal thermal performance. Consequently, it provides excellent cooling while maintaining a quiet environment.

Advanced Acoustic Optimisation (AAO) Frame:

Noctua’s proprietary AAO (Advanced Acoustic Optimisation) frame technology incorporates Stepped Inlet Design and Inner Surface Microstructures. These features work together to reduce noise and improve airflow efficiency. The fan’s A-Series blade geometry with Flow Acceleration Channels further refines airflow, ensuring quiet yet powerful cooling performance, with noise levels as low as 18.1 dB(A).

PWM Control for Precise Speed Adjustment:

The NF-A20 PWM supports 4-pin PWM control, allowing for precise and automatic speed adjustment based on your system’s temperature. This ensures optimal balance between cooling performance and noise levels. With a minimum rotational speed of 350 RPM at 20% PWM, it can operate virtually silently when cooling demands are low. Furthermore, the included Low-Noise Adaptor (L.N.A.) can further reduce the maximum speed to 550 RPM for even quieter operation.

Built for Durability and Versatile Installation:

SSO2 Bearing for Exceptional Lifespan:

The fan utilizes Noctua’s renowned SSO2 bearing, an optimized second-generation self-stabilizing oil-pressure bearing. This advanced bearing system ensures exceptional long-term stability and a lifespan of over 150,000 hours. Therefore, the NF-A20 PWM provides reliable and consistent performance for many years, backed by a 6-year warranty.

Flexible Mounting Hole Spacing:

The NF-A20 PWM offers versatile mounting options with spacing for 154x154mm, 110x180mm, and 170x170mm. This flexibility ensures compatibility with a wide range of PC cases and mounting points. Consequently, it simplifies installation in various system configurations, making it a highly adaptable cooling solution.

Comprehensive Scope of Delivery:

The NF-A20 PWM includes a comprehensive set of accessories for easy installation and versatile use. This includes a Low-Noise Adaptor (L.N.A.), a 4-pin y-cable, a 30cm extension cable, NA-AV3 and NA-AV4 anti-vibration mounts, and fan screws. This ensures you have everything needed for a hassle-free setup and optimized performance.
