Producto muy bueno, envío premium lento.
Noctua es símbolo de calidad aunque un poco caro son sus productos. Para Canarias no recomiendo los envíos premium ya que tardan lo mismo que los normales.

Noctua is the pinnacle of quality, elegance, and product support
The fan is so quiet, it’s impossible to hear anything. The fan is built super well, and comes with a variety of various connection. I was very pleasantly surprised that Noctua even included an adapter that I exactly would have wanted, which converts the connector to a red and black wire for soldering which is what I needed for my Ender 3. I was so impressed. Comes with all kinds of things in really nice packaging. This was an exceptional product experience. Up there among the very best. Noctua is top notch. I’ll be buying my fans exclusively from them from now on.

Running it inside Mikrotik CRS317-1G-16S+
Adding adding 10G copper transceivers, the stock fans were unbearably whiny because the copper transceivers run crazy hot. I swapped the stock fans to these and now all I get is peace and tranquility.

Excelente! Calidad Noctua.
Calidad Noctua. Para una fuente de poder ITX buscaba un ventilador con alto rendimiento y muy silencioso y Noctua es el ganador. En cuanto a presentacion desde el empaque notas la calidad premium de los materiales, la variedad de accesorios incluidos, la calidad del cable... En cuanto a rendimiento practicamente es imperceptible el ruido para la cantidad de aire que genera. Comparandolo con un Nidec no tiene nada que hacer el noctua, pero Nidec hace ruido y vibra como un mototool, aun a bajas RPM, en entornos industriales donde no importa el ruido Nidec es superior pues tiene mayor rendimiento ya que gira a mas altas RPM, Pero esque el noctua al 100% hace menos ruido que el Nidec al minimo que deja el PWM y no vibra nada, a similares RPM mueven el mismo aire, pero Noctua no se escucha nada, y nidec pues parece un mini taladro. Ni hablar, Noctua no tiene rival en relacion Rendimiento-Silencio.

Noctua NF-A4x20 PWM Premium 40mm Fan
Whisper quiet and moves a surprising amount of air for its size. You can feel the quality—definitely worth it for any small-form-factor PC build.
