    This product is great - I was anticipating installing the inline resistor, but this is so quiet that there really is no need.

    Packaging great. Fans are almost silent. Replaced 28P Switch fans with these. Wow what a difference. Stock fans were like jet engines.

    Although this was more than I intended to spend, I thought I would try one to replace a noisy fan in a varilight in my small home studio that was slowly driving me crazy. It came beautifully packaged with a variety of adapters and easy to install rubber shock mounts, was up and running in a few minutes, and is almost completely silent.

    Bought these to replace the jet engine sounding fans on my Reolink NVR. These were a direct replacement and were super easy to install. I did NOT install these with the low noise adapter, and still cut 10dB off the overall sound. Dont have anyway to measure temps before and after but the NVR is still cool to the touch, so Im happy.

    I bought this fan to replace a CPU fan in a bookshelf computer that was being used as a router box. The stock fan I got with the computer was extremely loud even during a minimum of load.

    Molto silenziosa ma con un buon flusso daria. Misurato con lanemomentro perde circa il 25% della ventola originale dellestrusore della stmpante 3D dove lho inserita, ma è immensamente più silenziosa: anzi non fa proprio rumore.

AAO frame

Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.

Flow Acceleration Channels

The NF-A4x10 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-A4x10 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 mounting systems and fan clips used on heatsinks.

Inner Surface Microstructures

With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.

Reduced motor hub size

Thanks to its streamlined, compact motor design, the NF-A4x10"s motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10"s superior airflow and pressure performance.
