Product Overview

The Noctua NF-A20 PWM 200 mm case fan is a large-format A-series fan that runs between 350 and 800 RPM and moves 100.8 to 146.9 m³/h of air at just 10.7 to 18.1 dB. Its AAO (Advanced Acoustic Optimisation) frame and Flow Acceleration Channels are designed to keep noise low at this size, and it uses an SSO2 bearing.

With a 4-pin PWM connector and Noctua’s NE-FD1 IC, the fan adjusts its speed automatically to balance quiet running against airflow. It suits large cases with 200 mm fan mounts where low noise matters, such as quiet gaming or everyday builds. The fan is screw-mounted, draws 0.96 W and measures 200 x 200 x 30 mm in the classic cream and brown Noctua colours.
