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

Replaced noisy fan on old Sony amp. This fan is obviously of a much higher build quality than the cheap OEM fan. Holes on this fan matched, but needed to enlarge chassis holes. Very versatile kit for mounting and electrical hookup. Oh, and QUIET... opted for max speed option and fan noise is imperceptible. China built, supposedly Austria designed.

I chose this fan because of the quality of manufacturing and reputation. It is to replace a cooling fan for a 12 volt power supply and works great, nearly silent in comparison to the original and easy installation.

Like all Noctua fans that Ive tried so far, this fan does not disappoint! This is the most quiet 60mm fan that Ive ever heard. Most fans this size are little screamers, but this one is so quiet that you barely even hear it running when the case is closed, even at full speed! The sound of the air being moved by it is probably louder than the fan itself, which is very unusual for a fan this small. I only hope that it can keep up this level of quietness throughout the rated life of the fan.

i like a lot of people have always used whatever cheapy fans ive had lying around for years in my builds. well i have a plex server that i had stuck some cheep 60mm fans into to keep the hard drives cool. they screamed. i finally decided i should try these since they have a good reputation. let me spell out how good these are.

not as quite as I had hoped but probably meets specifications. I have not tried the slower speed option yet.

Works as advertised. I replaced a noisy fan with one of these and used the 2400 rpm adapter and it is totally silent now.

This thing is shockingly quiet

This is small, quiet and works like a charm. I just wanted to add a fan to an old case that didnt have one and this fit just what I was looking for. I can only hear it because I have the pc sitting right next to my ear right now. At a normal distance and it cant be heard at all. The extra connectors that are included make it easy to install, even in an older case.

Used this to replace the noisy fan in my Anycubic Mega S 3D printer. Fantastic product and quality doesnt really get any higher.

Very quiet. Quality product.
