    je suis un grand fan de leur produit pour mes aircooling PC, cette fois cest sur une imprimante ender3 que jai avantageusement remplacé le ventilateur de corps de chauffe...bon maintenant il faut que je trouve des solutions pour atténuer le bruit des courroies, puisque je nentend plus quelles...impressionnant, merci Noctua

    Bought this for an internal case fan to help move enough air across the motherboard. It doesnt really help that much, but I dont want to hold that against it. I wanted a 60 mm by 10 mm Noctua fan, but they dont make a 60 mm fan that narrow when I bought this - they still dont.

    Der Lüfter ist wirklich sehr leise. Einige Steckeradapter liegen bei. Der Lüfter kann entweder mit Schrauben oder über beiliegende Gummihalter befestigt werden.

    Cè ben poco da dire su questo prodotto . Se cercate il meglio per quanto riguarda qualità e silenziosità . Il prodotto è perfettamente imballato e con tutti gli adattatori possibili per ogni tipo di esigenza ! Consiglio vivamente.

    This fan is incredible. It is so quiet. I used this fan to replace the 40mm fan that shipped with my Samsung SDE-4001 DVR. I wanted to keep this thing in an adjacent room to my bedroom but the stock fan is so noisy that I could hear it in the next room! The Samsung reviews are riddled with complaints about the fan noise but this fan is a direct replacement and completely solves the problem. The connector that matches up to the board inside the DVR is even included with this fan! I used the optional rubber bushings to mount the fan instead of the standards screws.

    I bought this to replace the fan in my old AV reciever as it sounded like it was taking off. This however is completely silent. Was going to buy a cheaper fan but bought this knowing how the good the brand is and is well worth the extra couple of quid.

    Quiet fan and includes a huge range of optional leads so you can connect it to almost anything.

    Beh, che dire? Le ho montate sulla mia stampante 3d. Quando L accendo non si sente un minimo rumore. Costano ma ne valgono assolutamente la pena. All interno della confezione troviamo un sacco di cavi e altri accessori. Scatola premium. Per queste cose non bisogna badare a spese. Sono fantastiche

    I mounted this fan to the heat sink of a LSI 9207 raid card and an Intel SAS daughter card to keep temps under control. Temps as measured by a Fluke IR heat detector, on the back of the cards, have gone from 130 degrees F, to 95 degrees F.

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.
