Fan Noctua 200x200x30mm 5V NF-A20-5V-PWM

The Noctua NF-A20-5V-PWM fan is a large 200 mm case fan that operates in the higher class for quiet and efficient cooling. It runs on 5 V, features PWM control, and comes in the typical Noctua brown color. The combination of large diameter, 350–800 RPM, and a noise level of only 18.1 dBA makes it suitable for builds where silence is a priority. The serious airflow of up to 86.46 CFM / 146.9 m3/h provides stable ventilation even at low speeds.

What you get

With dimensions 200 x 200 x 30 mm and several different mounting hole distances (154x154 mm, 110x180 mm, 170x170 mm), the fan is quite flexible for installation in more unconventional cases or modded projects. The SSO2 bearing is aimed at long life and stable operation, and the MTBF of 150000 hours indicates it is made to run for years 24/7. Thanks to the 4-pin PWM connector, you can dynamically control the speeds according to temperature, and the 5 V power supply and included USB adapter make it convenient for external solutions – test bench, NAS case, media center, even cooling via USB. The anti-vibration mounts help avoid parasitic noise from resonance with the chassis.

• Large 200 mm fan (200 x 200 x 30 mm), suitable for cases and projects that require serious airflow at low speeds.
• Wide range of 350–800 RPM, allowing for very quiet idle and sufficient airflow under load.
• Maximum airflow up to 86.46 CFM / 146.9 m3/h, providing effective cooling even in more enclosed cases.
• Extremely low noise level of only 18.1 dBA, suitable for silent and media PC configurations.
• Reliable SSO2 bearing and MTBF 150000 hours, aimed at long-term, continuous operation.
• 5 V power supply, USB connectors, and 4-pin PWM, plus OmniJoin adapter for easy integration into various systems.
• Rich accessory kit: 30 cm extension cable, NA-AV3 anti-vibration mounts, USB power adapter, and screws for flexible mounting.
• Various mounting distances – 154x154 mm, 110x180 mm, 170x170 mm, which facilitate compatibility with more cases.
• Long 72 months warranty, which complements the orientation towards long life and reliability.

Who it is suitable for

This fan is suitable if you are looking for quiet and efficient ventilation for a large case, silent build, HTPC, or custom project where 5 V power supply and USB connectivity are a plus. It is also a good choice for systems that run for long periods under moderate load and need reliable airflow without LEDs and visual effects. If you are looking for RGB and aggressive visuals, the focus here is more on acoustics and reliability.

The most meaningful aspect of this model is the combination of large 200 mm form factor, low noise, and flexible connectivity (5 V, PWM, USB), supported by a serious bearing lifespan and long warranty.
