Noctua NF-P14s redux 900 Fan, SSO Bearing, 140mm, Grey

This 140mm case fan is purpose-built for low-noise operation, making it suitable for general chassis ventilation or mounting on radiators. The unit maintains a fixed rotational speed of 900 RPM, which results in a maximum air flow of 83.7 CFM (142.2 m³/h). The fan generates a maximum static pressure of 0.77 mmH₂O while operating at a maximum noise level measured at 13.2 dB. Its design prioritizes quiet, consistent performance rather than maximizing high-speed cooling.

The unit incorporates SSO bearing technology, providing a mechanical advantage that supports an extended operational lifespan, rated at 150,000 hours Mean Time To Failure (MTTF). Construction uses PBT GF30 polymer material for both the frame and the nine-bladed impeller. Connectivity is managed through a standard 3-pin fan connector, operating on a 12V power source and consuming 0.84W of power. The package includes four screws required for installation into compatible chassis mounts or cooling hardware.
