Product Information
Full details
The Noctua NF-A20 PWM is a premium 200mm cooling fan engineered for PC enthusiasts who prioritize silent operation without sacrificing high airflow performance. It is designed for large computer case intakes or exhaust positions, offering superior build quality and advanced acoustic optimization. One caveat to consider is its 30mm thickness, which may require additional clearance in select compact cases compared to standard 25mm fans.

FAQs
Can this fan be used on a radiator?
While it is primarily designed as a case fan, its airflow and pressure characteristics are highly effective, though you should check that your radiator supports 200mm fans.
What is the primary benefit of the SSO2 bearing?
The SSO2 bearing provides superior stabilization, precision, and longevity compared to standard sleeve or ball bearings, contributing to the fan's 150,000-hour lifespan.
Does the fan come with the Low-Noise Adaptor?
Yes, the product includes a Low-Noise Adaptor (L.N.A.) that limits the fan speed to 550 RPM.
Is the cable length adjustable?
The fan includes a short 20cm primary cable and a 30cm extension, providing flexible options for cable management.
How long is the warranty?
The Noctua NF-A20 PWM is backed by a 6-year manufacturer's warranty.
Troubleshooting
Fan is not spinning at full speed
Check your motherboard BIOS settings to ensure the fan header is set to PWM mode and verify that the Low-Noise Adaptor (L.N.A.) is not currently installed.
Audible clicking or humming sound
Ensure all mounting screws are tightened appropriately to engage the silicone anti-vibration pads and confirm no cables are making contact with the fan blades.

Setup, Compatibility & Care
Before installation, verify that your PC case has 30mm of clearance, as this fan is slightly thicker than the standard 25mm aftermarket options. Use the provided 4-pin PWM Y-cable to connect multiple fans to a single motherboard header if necessary. The integrated silicone anti-vibration pads should remain attached to the frame to prevent rattling. To maintain peak performance, periodically check the fan blades for dust buildup and clean them with a soft brush or compressed air, ensuring you do not use liquids that could penetrate the bearing seal.
