Le silence
Très très très silencieux, un peu léger pour le refroidissement mais c'est parfait pour mes besoins

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.

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!

Well Worth the Money Spent
Noctua NF-A4x10 5v PWM FanIn my opinion, these fans live up to their premium quality advertisement. Build quality is excellent, noise is very minimal, and the 40 millimeter depth allows for extra airflow. You may not enjoy the color but I'm confident you will enjoy the quality and performance. Used to cool to steering wheel pedal sets they perform quite well and are nearly silent. Cooling is very efficient. These can be mounted with screws or with the included rubber grommets. Please bear in mind these are for 5 volt current not 12 volt. They will work with both PWM or direct voltage applications
