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.

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

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!

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.

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.

Really quiet
Its a shame these are so expensive, but then you get what you pay for. Super quiet and excellent build quality.
