NoctuaNF-A14 ULN, Ultra Quiet Silent Fan, 3-Pin (140mm, Brown)

Very quiet fans with moderate airflow.I got these to replace the stock fans in my Fractal Designs midi case which were getting a bit rattly.An easy swap using the elastomer spike mounts.Results are impressive; very quiet indeed. Airflow is less than before but case temps are no higher, even under heavy load.Not cheap but a quality product.

I have three of these Noctua fans in a custom-built PC (Ryzen 7 3800X + 4 x large SSDs) for use in a music studio where background noise level needs to be very low. I cannot get over how quiet that are. When running normally, they are nearly silent - and that is without the noise reducing cable (supplied with each fan). They are not cheap but you have to pay for quality and these are certainly quality fans!Very pleased and would definitely recommend if fan noise is a concern!!!

Top quality fan. Slightly tricky to install the rubber noise-reducing plugs but that is due to space restrictions in my case. Very quiet and good as a case fan. Note that air flow and pressure is sacrificed for low noise, so choose wisely.

Once installed, these Noctua ULN fans are very, very quiet - not silent - but close enough. Using four of these in my Corsair 600Q lowered my case temps by about 4-5 degrees, compared to my previous Be Quiet! Silent Wing 2 fans, which I thought was a great result. Added to this was the excellent service I received from Noctua, with next day dispatch and helpful support. In my opinion, it's well worth paying the extra for this brand.

Virtually silent at full speed 11.9 dB(a) while still running at 800 speed and providing a airflow of 79.8 (m3/h). So to put it another way..this is the best fan in my opinion you can buy. One at front and one as a exhaust and the noise and temperatures both decrease brilliantly. Also..in the box you get a extension lead to ensure you can get power to it anywhere in your case and also a few speed control connectors if you want to slow it down from the top speed which with this make I never do as they are so quiet.

I installed in a Phnateks P500A case using the Ultra Low Noise adapter running power directly from the PSU (not via a motherboard fan header).My PSU and GPU both only run fans at medium to high load, and passive cool normally. My AMD Ryzen 5 3600 CPU cooler is stock, but fan controlled (motherboard) to be virtually inaudible - far quieter than this. The stock Phanteks case exhaust fan is far quieter than this, again almost inaudible, and runs from a speed controlled motherboard header.This fan is very quiet, I tested the pc at the side of the desk I was sitting at. It was very quiet but easily audible.I then went three to four metres away, on the other side of the desk from the fan. It was still very quiet, still obviously audible.This is a great fan, it shifts what seems like a lot of air, it is very quiet but it does make some noise.

These fans are beyond awesome. There is just no competition. Long lasting (7+ years) and ultra quiet. A little bit more expensive than the cheap Chinese fans, but you get what you pay for. Definitely worth their price, I highly recommend them!

very good fans and still going strong.

Yes it came three days late, who cares. I rarely write reviews but this one time I will. I am using this as an - external - fan I placed on top of my fanless Mini ATX PC to cool the surface a bit. (to usb port) Meaning, the fan actually sits on top of the machine and the machine is about 2 feet away from my keyboard. Reason I invested in a fanless PC is that I am particularly sensitive to mechanical noise.Can't hear this fan. I tried. I just cannot hear this thing. Not an excessive amount of air flow but silent. Not whisper quiet, silent.It does cool the internals of my machine a bit more, I placed the fan one inch above the vent, super nice build, and silent.Why did I not do that earlier ?

It's silent and works as designed, still for only 800 max rpm 3 pin fan it's quite pricey.

Son una pasada, sin duda alguna los mejores.He puesto dos en el frontal de la caja y no hace nada de ruido, pero tienen un caudal tremendo.El diseño quizás no pueda gustar a todos pero a mi me encanta.Viene con varios accesorios como cables alargadores, el atenuador de DB y el sistema de montaje insonoro con "tornillos" de goma.El packaging esta muy cuidado y te hace sentir que es premium desde el primer momento.

Dead quiet. I knew that Noctua was an amazing brand when it comes to fans, and was not disappointed by this first purchase from them. The only thing that I had a bit of issue was from the anti vibration mounts, they were a bit hard to install, so I recommend doing so before installing your motherboard and other components. Having some pointy and small pliers really helps as well.Seriously though, these fans are good, I'll definitely use this brand from now on.

Esta cosa en verdad es silenciosa. No se ve tan apantallante como el DS de aerocool pero es mucho más silencioso, casi es inaudible. Si puedes pagarlo, cómpralo. Lo uso como ventilador auxiliar para sacar aire caliente.
