NoctuaNF-A8 PWM, Premium Quiet Fan, 4-Pin (80mm, Brown)

This fan cost a little more than some other brands but you can tell is very high quality part. Also it included an extension cable, a “Y” splitter cable, and a cable that lowers fan speed if running of uncontrolled header, all of which would cost extra if not included. My mother board only has one fan header for the CPU, with this I was able to use the splitter and run both cpu cooler fan and case fan off one header. A bonus of doing it this way is that the case fan is speed controlled by the cpu temperature so runs quiet or turns off when not needed and spins up when computer gets hot. No wasted money for RGB lights only whats needed.

Excellent packaging, instructions, build quality, and attention to detail.Silent. Incudes adapters, and hardware.Less expensive than generic alternatives that might take weeks to ship.This Austrian company seems to only make these fans.Buy!

This brand of fan is excellent. They are as quiet as advertised. The packaging is a bit of over-kill. But, it does make for a nice presentation. I bought two of these fans for my HP Medismart Server and another for the new PSU I installed.I chose to use the included silicon mounts, but they needed a slight modification to work. The heads were much to big to fit through the mount holes in the chassis. So, I used a punch to make them smaller.I measured the decibels before and after replacing the fan in the PSU. These larger two fans had already been installed. This brand of fan has made a huge difference in the sound coming from my server.

This review is for both the 92mm and 80mm versions of this model, 4-wire units with speed controlled by the motherboard.If you're like many consumers, you accept the cooling fans installed by the manufacturer, and look at fans like this and their cost, and say "meh".Ironically, I'm am/was IT professional in the same situation...However, when I finally got around to buying a new server [versus hand-me-down units] for use at home, the fan noise that I accept at work [in a separate IT room] became unacceptable in our home office.Did some research and found this brand. Admittedly there are other makes/models out there and I'm approaching this as a fan newbie...I can summarize our findings by saying that my keen-eared better half questioned whether the server was actually powered on... that much drop in noise levels.Using the server's built-in hardware monitoring, fans are running at about 50% of top RPMs for the case fan [this 92mm] and at about 70% for the CPU fan [an 80mm] and temperature swings have abated along with the noise. These move the air a lot and with their blade design coupled with the cushioned mounts, do it very quietly.The fans ship with a short power jumper that shifts the fan speeds to an even lower range with a drop in maximum speed, and this works quite well, dropping fan noise to totally inaudible. Due to the presence of four 3.5" spinning drives in the server case [and their heat], I erred on the side of caution and restored the fans to their native speed range, with only a slight difference in noise, and no change in temperature/cooling.Based on experience so far, I can't praise this line highly enough...

Quiet and does amazing cooling high rpm speed barely makes sounds, worth the money

There's no doubt this is the top of the line PC fan. It's quiet, and has adapters to adjust the speed if you don't have a fan header that controls speed avaialble. I have used these in 2 recent PC builds - one was with an HP I got on ebay that I wanted to improve case air flow, and one for a very small form factor build I was doing with the old components from my PC after building a new one.

Fast shipping, love these little U1 fans i have them in my rack switches and servers will buy again.

My 80mm case fans (really old Antec case) came with everything needed to install them. That included soft, rubber mounts as well as screws, short and long cable extensions, a splitter cable from which to run 2 fans from one fan header, and a 6 year manufacturer's warranty.When the computer is idling, the fans are barely audible. Once the processor goes to work (Ryzen 9 9750X3D using integrated GPU) I can hear fans speeding up slightly but they are still very quiet.I'm a great fan of Noctua fans and will buy again if needed.
