Summary: Whereas the fan quality is high it only comes with the fan itself and 4 screws. No nice accessories that you may be accustomed to coming with Noctuas more expensive models. Also there is not any rubber grommets around the screw holes which you also may be accustomed to.
Pros: For the Redux series of Noctua fans you get the premium Noctua quality fans for a fraction of the cost. See other thoughts for what you sacrifice. The fan is quiet and moves air, it does what it was intended to do.
Summary: I was looking at this brand a while back but hated the brown / tan color scheme. When I saw these on sale I bought 4 of them right off the bat. Totally worth it. I sometimes forget that my computer is on when I am in my room.
Pros: These are VERY quiet, I absolutely love these fans. They are very well built fans. The loudest fan In my PC now is the Graphics card, and I just adjust that in my settings. I can fall asleep with my computer on now easily, and while watching movies there isn't a loud droning from fans in the back...
Cons: The only con is the price, but you have to pay for quality.
Pros: Bought this fan based on my previous experience with Noctuas (new ones installed just yesterday.) These fans are great: great coolers, well designed, and as quiet as could be. A friend recommended Noctua fans to me and I recommend them to all reading this post.
Cons: The only con with this particular fan: it didn't come with rubber "screws." Admittedly, I should have known; in my haste, I neglected to read the "fine print."
Summary: Ya tengo experiencia con otros productos de Noctua y compré este ventilador esperando calidad y eficiencia. Justo lo que ofrece. En mi torre, ANTEC P193, con una temperatura ambiente en la habitación bastante alta, suele funcionar auto-regulado entre 900 y 1000 rpm y a esas velocidades es muy...
Summary: Tiene un buen acabado a falta de los detalles de los modelos normales de Noctua, sin las sujeciones ni los recubrimientos antivibración. Pero es silencioso, mueve un buen flujo de aire y es más barato que los modelos convencionales del fabricante.
