    The fans are dead slient at 7V & even with adapters at 9V, only wish it was producing less noise at 12 V.

    Amazing. Replaced the stock 140 mm in my 750d. Quiet and increases airflow over the stock fan. Just received and installed my second one today. By next week, all my fans will be replaced. Quality is great and I cant recommend this enough!

    Yes its very quiet at max speed/rpm. Packaging is top quality, comes with evrything you need such as, rubber mounting, fan screws, 4 pin molex adaptor, cable/extender, and low noise adaptor. Very high quality, poor aesthetics which is not a big deal for me. Used it as a pull, so i can hide it behind the radiator.BUY IT!

    These fans are of the highest quality, Very silent at 5v, but can get noisy at full blast cause they move a lot of air, but not cause they are loud per se.

    I use these with the included Ultra Low Noise Adapter. They spin nearly silently, and airflow is slow enough as to not create additional noise.

    I love noctua and am glad that I can get such a great deal on amazon prime. I would like to tell you about the Noctua NF-A14. It is not as good as the P series because it does not spin at as low of voltages. The build quality is noticeably worse than the P series in that it is lighter and feels less rugged.

The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO(Advanced Acoustic Optimisation) standard. Its square shape and 140mm mounting holes (124.5mm spacing) make it ideal for use on watercooling radiators or as an upgrade for 140mm case fans. Featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A14 further improves the renowned quiet cooling performance of the award-winning NF-P14. The FLX version provides 1200/1050/900rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.

Flow Acceleration Channels

The NF-A14 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.

SSO2 Bearing

The NF-A14 features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.

Integrated anti-vibration pads

Integrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
