## Summary description

Noctua NF-A20 PWM is a 200 mm computer case fan with a 4‑pin PWM connector and SSO (self‑stabilising oil‑pressure) bearing. It delivers up to 146.9 m³/h airflow at 800 RPM (min 350 RPM, LNA mode down to 550 RPM) and maximum air pressure 1.08 mmH2O. Noise ranges from 10.7 dB (LNA) to 18.1 dB. Powered at 12 V, 0.96 W, MTBF ~150,000 h. Includes fan cable, low‑noise adaptor and four mounting screws. Suitable for improving case ventilation and cooling components.

## Long description

The Noctua NF-A20 PWM is a premium 200 mm computer case fan engineered for quiet, efficient cooling. It combines Noctua's Advanced Acoustic Optimisation (AAO) frame with aerodynamic features such as Flow Acceleration Channels, Stepped Inlet Design and Inner Surface Microstructures to improve airflow, pressure and noise performance. The PWM model uses Noctua's NE-FD1 IC with Smooth Commutation Drive (SCD) for automatic 4-pin speed control, and the fan is built on the second-generation SSO2 bearing for long-term stability and durability.
Advantages
The NF-A20 PWM delivers a balance of low-noise operation and ventilation performance by using aerodynamic blade geometry and an AAO frame with integrated anti-vibration pads. Flow Acceleration Channels and Inner Surface Microstructures reduce flow separation and blade-passing noise, while the Stepped Inlet Design reduces tonal intake noise and improves suction. The custom NE-FD1 PWM IC with SCD reduces PWM switching noises at low speeds, and the included Low-Noise Adaptor (L.N.A.) lets you cap maximum speed for quieter operation. Multiple mounting hole spacings and extensive cabling options increase compatibility and installation flexibility.
Suitable for
PC cases that support 200 mm intake, exhaust or side-panel fans
Quiet workstation or home-theater PC builds requiring low acoustic noise
Replacement for lower-quality 200 mm, 230 mm or 250 mm fans (using compatible hole spacings)
Key specifications

Included accessories: Low-Noise Adaptor, 30 cm extension cable, 4-pin Y-cable
Warranty / reliability: MTTF \> 150,000 h; 6-year manufacturer’s warranty
Color: Beige / Brown
How to use
Mount the NF-A20 PWM using the appropriate hole spacing (154 x 154 mm, 110 x 180 mm or 170 x 170 mm) to match your case or bracket. Connect the 4-pin PWM cable to a motherboard fan header that supports PWM control for automatic speed adjustment. Use the supplied extension or Y-cable if additional reach or multiple-fan control is required. If lower maximum RPM is desired, attach the Low-Noise Adaptor to limit the top speed to 550 RPM or run it at a fixed reduced speed.
Usage recommendations
For optimal acoustic and cooling results, install the fan in a position that promotes unobstructed airflow and use the PWM header for automatic control. Ensure screws do not compress the anti-vibration pads excessively to maintain vibration damping. Replace the fan only with compatible mounting spacing to preserve case compatibility.
