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

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!!)

Seems to be built well and is very quiet. Obviously as you increase the speed you will hear some noise but its not high pitch and is just noise of air being moved not bearings or anything like that. Comes with bunch if adapters including 2 fixed speed adapters.

80% of the CFM air of the original fan in my Meanwell SE-600 power supply, but rather than sounding like a jet engine, it now sounds like a breeze. The original fan was 44db, this is around 23db but once the enclosure is closed, you have to get within 3 inches to hear it at all.

Surprisingly quiet for a 60mm fan, even at full load. This is to be expected, though: Noctua makes some of the quietest fans around.

These are a great replacement for the fans on my off-grid inverter. They have always been loud, but lately the bearings have started to wear, and they sounded like a jet fighter taking off. These Noctua fans are much quieter, and the noise is easily covered by the fridge and other equipment powered by the inverter.

This fan is probably the best fan out there for server cooling. It is also the best replacement fan for Thrustmaster video game wheels. It is awesome as advertised. The cooling fan comes with tons of adapters and instructions. I wish everything I bought was as good as this...

Fast, quiet, elegant and modern. Don’t be fooled they really undersale this fan. Once in hand you can truly feel the quality. I am using four to cool a terrariums lighting. Only fan I’ll be using in the future.

This fan is listed as a 12v fan at 0.120 Amps. The fan shipped to me only pulls half that current at 12v (0.06 amps). I am surprised they have a CE RoHS rating on the package.

I bought this to replace a tiny noisy fan in my Schumacher battery charger.

I used this to modify the power supply for my XBox One. The original fan was simply too noisy, too difficult to clean, and a pain in the butt to source new. Had to severely modify the power supply box to get it to fit, but it only required a battery powered Dremel and a Swiss army knife.
