Fan Noctua NF-A20 PWM CH.BK.S — 200 mm PWM computer case fan, 12 V, 350–800 RPM, 146.9 m³/h, SSO bearing

The Noctua NF-A20 PWM chromax.black.swap is a 200 mm case fan that combines Noctua’s quiet cooling technology with an all-black appearance and interchangeable anti-vibration pads. Designed for efficient airflow in PC builds, the fan uses Noctua’s SSO2 bearing for long service life, supports PWM speed control from 350 to 800 RPM, and delivers an airflow of 146.9 m³/h with a maximum static pressure of 1.08 mmH2O. The compact 200 x 200 x 30 mm format and included red, white, blue, green, yellow and black pads allow colour customisation to match individual system aesthetics.

Advantages

The NF-A20 PWM chromax.black.swap offers quiet operation thanks to its self-stabilizing oil-pressure (SSO2) bearing and optimized blade design, high reliability with a mean time to failure of over 150,000 hours and a 6-year manufacturer warranty, and flexible visual customisation via swappable anti-vibration pads. PWM control enables precise speed adjustment for balanced cooling and low noise across a wide RPM range.

Suitable for

• High-airflow case cooling in mid-tower and full-tower PC builds
• Systems where low noise is required (silent or home office PCs)
• Custom builds that require visual colour coordination

How to use

Install the NF-A20 PWM into a compatible 200 mm fan mount in your computer case, aligning screw holes and securing with the supplied screws or mounts. Connect the fan’s PWM cable to a motherboard fan header or PWM fan controller for automatic speed regulation. Swap the included anti-vibration pads by removing the existing pads from the frame and inserting the desired colour pads into the pad slots to match your build’s colour scheme.

Recommendations

For best results, use the NF-A20 PWM with a PWM-capable motherboard header to allow automatic speed control. If you prioritise the lowest possible noise, configure fan curves in BIOS or a fan-control utility to keep the fan within lower RPM ranges during light workloads. Ensure the fan is mounted securely and that airflow direction matches your case cooling plan.
