Noctua NF-A20 PWM 200x200x30mm Fan

Are you looking for a large and quiet fan for your case? Noctua NF-A20 PWM 200x200x30mm is a 200 mm fan aimed at quality airflow with minimal noise. With a thickness of only 30 mm and PWM control via 4 PIN connector, you can easily fit it into most cases and cooling profiles. It operates in the range of 350–800 RPM, and the noise is only 18.1 dB(A), making it suitable for a quiet system or living room setup.

What you get

With a size of 200 x 200 x 30 mm, the fan covers a large area of the case panel, allowing it to move more air at lower speeds. The flow rate of 146.9 m3/h, combined with a maximum pressure of 1.08 mm H₂O, is more than sufficient for effective intake or exhaust even in larger cases. Thanks to the dynamic fluid bearing, the fan is designed for long and reliable life, with an MTBF of over 150,000 hours, meaning years of 24/7 operation without drama. The consumption is modest – only 0.96 W at 12 V and 0.08 A, so it doesn't burden the power supply and motherboard, while PWM control gives you control over the speed and noise according to the system load.

• Large 200 mm form factor, allowing strong airflow at lower speeds and less noise.
• Wide range of 350–800 RPM, giving you flexibility between maximum silence and more serious cooling under load.
• Flow rate of 146.9 m3/h, suitable for large cases and optimizing overall airflow in the system.
• Maximum pressure of 1.08 mm H₂O, which helps air pass through filters and denser mesh panels without choking.
• Low noise level of only 18.1 dB(A), suitable for quiet or bedroom configurations and media PCs.
• Dynamic fluid bearing and MTBF of over 150,000 hours, ensuring long-term reliability and stable operation.
• 4 PIN PWM connector for precise speed control through the motherboard and automatic adjustment according to temperature.
• Classic brown color and lack of RGB lighting – focus on function and silence, not a light show.
• Long warranty of 72 months, securing your investment in quality cooling.

Who it is suitable for

This fan is suitable if you are building a quiet or high-airflow case and have space for a 200 mm fan at the front or top. It is ideal for gaming and workstation configurations that run for long periods and want stable temperatures without excessive noise. If you are chasing an aggressive RGB look or your case does not have 200 mm mounting positions, it is better to opt for a different size or RGB series.

With the combination of large size, low speeds, quiet profile, and serious durability, the Noctua NF-A20 PWM is a very sensible choice if you value real cooling and silence over lights and decoration.
