Noctua NF-A6x25 FLX, Premium Quiet Fan, 3-Pin (60mm, Brown)

Nearly silent, moves a decent amount of air, cant complain.

Is perfect, but no like so much the brown colors, the rest is ok and silent, I recommend, is ok.

This is an amazingly quiet fan. Packaging is way better than expected. The quality of engineering is very good. It replaces a cheap Chinese generic fan. It is four times the price, but I am confident it will last ten times as long with much less noise. (I cannot hear it in my application. I use it to exhaust air from a kitty litter box to the outside. No odors in the house!!)

Im constantly upgrading the audio components in my Home Theater system, the latest component was too deep to fit in the cabinet I had built a few years ago so I decided to build a new cabinet. Took my time (almost 3 months). I installed six 60mm fans to keep the components cool. I was very pleased with the outcome except for one thing...the fans were extremely loud, they were powered by an adjustable voltage supply and even at lower speeds they were still screamers, so much so, that I could hear them at anything less than concert-level music! I replaced the fans with these Noctua fans and I have to say Im impressed! Even at full speed, the noise is pretty much non-existent.

Nice quiet fan and good airflow for the RPM...

Have an Ender 3 Pro and upgraded my PSU fan. Super quite. I replaced all of the fans with Noctua fans.

Like other reviews mentioned, this is very quiet. And being an overpriced brand name, will hopefully last well. But it doesnt move a lot of air, and my biggest objection is they didnt include screws. I had to go to the hardware store and of course they didnt have any #4 screws long enough... They include the wide screws you might use to mount it to a case, but I was replacing a CPU fan atop a heat sink. The previous one was only 10mm, and had screws, but this one is 25mm thick (which was fine cause I have the room for it) and did not include 30mm screws. Had a BUNCH of other adaptors, etc, that I didnt need, but not screws that were long enough to go through the fan.

Great quality and quiet fans. I personally also love the color.

Fit great with rubber insulators.

I have run Noctua fans for over a decade in countless computers I have fix and built. However, this is the first time I have used them in an automotive application. Im using these in a custom enclosure to cool my communication equipment. They are controlled by relay when the equipment turns on. I will try to remember to update this review in the future. Im curious to see how they will do in the summer heat inside a vehicle.
