Product Description
Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x10 is an award-winning, premium-quality quiet fan in size 40x10mm. The PWM version sports Noctua’s custom-designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise Adaptor as well as an OmniJoin Adaptor Set for easy connection to proprietary fan headers. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.
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 ChannelsThe 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 BearingThe 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 PadsIntegrated 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 MicrostructuresWith 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.

Also, the brown color has grown on me as many computer enthusiasts AND 3d printer enthusiasts regard the brown color on these fans as a "See? Look at how I made my thing better than it once was."
Perfect for 3d printer!

There's a reason people use Noctua brand fans in their computers; they're quiet without sacrificing performance. After years of having Noctua fans in my computer, it was only natural that once I got a 3d printer and set it up in my bedroom, that the stock fans had to be upgraded. I don't have a decibel measuring tool but I don't need one to notice the clear difference.Reviewed in the United States on November 24, 2023

Leiser Premium-Lüfter für effiziente Wärmeableitung und verbessertes NZXT H1 V1-Setup

Das Design und die Verarbeitung des NF-A4x10 PWM sind typisch für Noctua - solide und zuverlässig. Auch wenn das klassische Braun vielleicht nicht jedermanns Geschmack trifft, ist es doch ein Markenzeichen und sorgt dafür, dass man den Lüfter sofort als Noctua-Produkt erkennt.
Was mich jedoch am meisten beeindruckt hat, ist die Lautstärke dieses Lüfters. Dank Noctuas SSO2-Lagersystem und der PWM-Steuerung bleibt er auch bei höheren Drehzahlen angenehm leise. Das ist besonders wichtig für mich, da ich einen leisen Betrieb meines PCs bevorzuge.
Da ich mit dem NZXT H1 V1-Gehäuse arbeite, das bekanntermaßen mit Wärmeproblemen zu kämpfen hat, habe ich mich entschieden, gleich drei Noctua NF-A4x10 PWM-Lüfter zu nutzen, um die warme Luft aus dem Gehäuse effizient abzuführen. Die Kombination aus geringer Größe und gutem Luftstrom macht diese Lüfter ideal für den Einsatz in engen Gehäusen wie dem meinen.
Die PWM-Steuerung ermöglicht mir eine präzise Regelung der Lüftergeschwindigkeit, basierend auf der CPU-Temperatur. Dadurch kann ich sicherstellen, dass meine Komponenten optimal gekühlt werden, ohne dass der Lüfter unnötig laut wird. Die automatische Anpassung der Drehzahl an die thermischen Anforderungen meines Systems ist einfach großartig.
Natürlich ist der Preis des Noctua NF-A4x10 PWM etwas höher im Vergleich zu anderen Lüftern derselben Größe. Aber meiner Meinung nach rechtfertigen die Qualität, Leistung und der exzellente Kundenservice von Noctua diesen Preis. Es ist beruhigend zu wissen, dass ich ein Produkt habe, auf das ich mich verlassen kann.
Insgesamt bin ich mit dem Noctua NF-A4x10 PWM sehr zufrieden. Die Kombination aus leisem Betrieb, effizientem Luftstrom und präziser Steuerung macht ihn zu einer ausgezeichneten Wahl, insbesondere für Nutzer wie mich, die ein NZXT H1 V1-Gehäuse verwenden und mit den Wärmeproblemen zu kämpfen haben. Wenn du auf der Suche nach einem hochwertigen und leisen Lüfter bist, kann ich den Noctua NF-A4x10 PWM definitiv empfehlen.
