Noctua NF-A20 FLX Fan, SSO2 Bearing, 200mm, Beige/Brown

This 200 mm case fan is engineered for system builders requiring high volume airflow across large chassis dimensions. The design utilizes an AAO (Advanced Acoustic Optimisation) frame, which contributes to overall cooling efficiency and reduced turbulence noise. The impeller incorporates Flow Acceleration Channels, a feature intended to increase air speed towards the blade tips for improved static pressure performance. The fan is rated for use in various case locations, including intake, side-panel, or exhaust configurations.

The fan operates on a 3-pin connector and does not feature Pulse Width Modulation (PWM) control. Maximum rotational speed is specified at 800 revolutions per minute, generating an airflow of 146.9 m³/h and an air pressure of 1.08 mmH2O. At this peak setting, the fan generates a measured noise output of 18.1 dB. Reliability is maintained through the use of an SSO2 bearing technology, supporting a rated lifespan (MTBF) of 150,000 hours.

The included Low-Noise Adaptor (LNA) provides an option for reduced operation, lowering the maximum speed to 550 RPM. Using the LNA results in reduced noise production, measured at 10.7 dB, suitable for acoustically sensitive environments. Power consumption is rated at 0.96 W at 12 V operation, providing low electrical draw relative to its performance profile. The product includes necessary mounting hardware for installation.
