Great for a Raspberry Pi case!
I bought this fan as I wanted to use it as an extractor on a Raspberry Pi case - I needed something small, silent and low voltage so it could be run from the Pi's USB ports.This fan achieved all those goals and more!It came with a USB adapter, which left the cable pretty long - too long to go a few cm into a USB port on the side of a Pi - so I cut the wires and soldered the USB connector directly on to the wires leaving the fan housing - very simple to do thanks to the nice design from Noctua and it's happily doing its job of keeping a Raspberry Pi nice and cool.Obviously at 5v it doesn't have a lot of oomph, but for its size and how silent it is, it does move a good amount of air.Impressed and recommended for smaller projects such as Raspberry Pi based builds!

Teeny USB powered quiet fan, perfect!
Purchased for a 3D printed project, works an absolute treat! So long as Noctua fans stay consistently great I'll be consistently brand loyal, nice and quiet with good airflow.

This is really silent. It comes with nice packing and useful accessories. Great choice if you need a really silent cooling fan.

Best Cooling Fans you Can Buy
Best cooling fans you can buy. Used a lot of these fans of various size and voltage. Very quiet and efficient. Many connection cable options are provided for speed control or direct control together with low noise/vibration mounting pieces. Very long working life with sealed bearings and a six year Warranty. Highly recommended.

A itty-bitty tiny and quite fan
It's so small that it is cute, its very silent and works as any other Noctua fan (considering the size).

Nice usb powered external cooling.
I bought this fan as I am designing a 3D print external cooling solution for my Surface 7. In trials this fan is very quite and shifts a good amount of air. The Surface 7 is cooled somewhat in testing as planned. I made another one of these into a portable personal fan [just because] and that works well too.Make no mistake! This fan is usb 5V powered - not to be used inside a PC [from motherboard header etc] as these are 12V.

The king of fans!
If you've found yourself here, then you probably already know that when it comes to fans, Noctua ones are one of the best.They are fantastic quality and reliable and probably the most important part, quiet.They're normally drop in replacements, so it's easy to switch out a noisy fan to a noctua.As a premium product, they are expensive, so it's a balancing act.

Quality product
As you'd expect from Notus. Not the cheapest but also extremely good.

Silencioso
Increíble cómo algo tan pequeño puede mover tanto aire sin sonar como un mosquito enfadado. Lo he usado para sustituir el ventilador de serie de una impresora 3D y el cambio es brutal; ahora el silencio es casi total. Noctua nunca falla con la calidad de sus rodamientos.

Klein, leise und zuverlässig – typisch Noctua
Der Noctua NF-A4x10 5V PWM ist für mich einer der besten Lüfter in dieser Größenklasse – da gibt es eigentlich nicht viel zu sagen. Die Verarbeitung ist, wie von Noctua gewohnt, erstklassig und der Lüfter arbeitet trotz seiner kompakten Abmessungen angenehm leise. Dank der PWM-Regelung lässt sich die Drehzahl präzise anpassen, sodass bei geringer Last kaum etwas zu hören ist und bei Bedarf trotzdem eine überzeugende Kühlleistung zur Verfügung steht.Zum Lieferumfang gehören zudem hochwertiges Zubehör wie Entkoppler und Adapter, sodass einer unkomplizierten Installation nichts im Weg steht.Wer Wert auf Qualität, Langlebigkeit und einen leisen Betrieb legt, macht mit diesem Lüfter nichts falsch.Klare Kaufempfehlung!

Quiet and effective in a 1U server
I’m using these in a 1U server and they work great at keeping the hard drives cool. They move plenty of air for their size and are surprisingly quiet, especially compared with the fans that came with the server case. Very happy with them.

Ottima
Ventola molto silenziosa. Arriva con una ricca fornitura di cavi ed accessori per la sua installazione. La sto adoperando per raffreddare un hotspot su base Raspberry Pi 3 Model B Plus, che si sa scalda molto. Bene riesco a mantenere una temperatura compresa tra i 28° ed i 36°. Prova superata a pieni voti. Consigliata.

Excellent
The added USB cable saved me a lot of headache. Really good documentation on the cable colors. All in all a very good fan :)
