NF-A9 PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (92mm, Black)

I had a need for smaller fans for a small case. In keeping with good Noctua quality and consistency, it did the job and is quiet. It's kind of pricey as all Noctua stuff is. Airflow and static pressure are kind of wimpy, but average for a fan of this size. Cable length is okay. Wished it came in other colors like white, gray, yellow, red, etc.

OK so more serious I upgraded form a 3600 to a 3900X and figured i could use a bit more cooling since the 3900X are known to run hot. Well with my unique system there is a need for unique cooling solutions ,and I like em quiet. PROS: This fan is actually somehow quieter than the Original Brown fan 14mm thickness, ,but it is 25mm thicc. Mounts right up without having to take cooler off, And the box is super nice like all noctua products. It provides better cooling by 2-4 degrees, I run at 50 at idle and 60 while flat out the 3600 ran at about 10 degrees cooler. My system is built for minimal noise and minimal fans. Everything is Perfectly silent. If you need a quite 92mm fan go ahead and buy this. I also like Be Quiet! Silent Wings or Dark Wings for case fans but Noctua is the way for Small and effective. and the L9 is the perfect cooler if you are tight on space and this fan gets you the looks you want. ok here is the CONS Its thicker than the original fan , but this is only a negative if you cant spare the extra 11mm and it s so quiet that you cant tell if its even running. im not sure if its legal to be this quiet. and final thoughts every Noctua product i have tried so far has well beaten my expectation and i will recommend them to anyone with any need, especially if you needs are good cooling and shhhhhhhhh.

As expected from Noctua, this fan seems very well built. It runs smoothly with very minimal vibrations and is extremely quiet even at full speed. It was clearly designed more for silence than performance though since it doesn't move a huge amount of air even when running at full speed in open air. I'd say it has about average performance for a 92MM fan with much lower than average noise. It would be nice if this fan had a bit higher maximum RPM in case more cooling is ever needed since it could always be turned down if it's too loud but can't go higher than 100%, but since most people buying Noctua fans are probably mostly doing it for the silence and wouldn't normally be running it at full speed anyways, this wouldn't be a drawback to most of their customers.

When the fan went out on my 12 year old PC, I looked at replacing the fan with stock, but this one had next day shipping. I am SO VERY glad I ordered this one. I used to have a jet engine next to me anytime I was running more than a few programs at one time. Now, my computer hardly makes any noise. I can feel the amount of heat its pumping out the back side, but the fan itself is so quiet. Would highly recommend this fan.

Added 2 of these Noctua NF-A9 92mm CHROMAX. BLACK. Swap fans to my Thermalright Silver Soul 110 Black. Now my Lenovo P520 Workstation is running super cool. Best 92mm fans on the market. Thanks Noctua! 👍

Quiet, powerful and exactly what I needed to cool my case. The size and cable length were perfect for my scenario. I have an HP tower that is notorious for being under ventilated. I used this fan, a new noctua cpu air cooler and a couple other noctua fans that instantly changed my computers performance. I'd never used noctua fans before, read great things about them, but the price seemed outrageous to me. I went from 85 degrees Celsius in my case on a regular basis just doing basic video streaming, to solid stable temps never above 60 degrees celsuis. This was part of a system of fans that changed the game for me. Highly recommend, superb quality.

Used for perfect fit replacement in my Ugreen NAS! Definitely quieter and cooler than the stock OEM fans.

High-quality build, very quiet on low-mid rpm. Using for rear-intake on Ncase M2, giving sufficient airflow. It gets pretty loud as it gets to high-max rpm. I used Noctua NA-FD1 as a space between the case and the fan which I think it helped to reduce a bit of fan noise.

Conforme à la description, produit de qualité

The rear exhaust fan on my HP Z440 was noisy and rattly 'AF'. Replaced with this fan. Boom, the noise is gone. Considering it is only a 92mm fan, it's extremely quiet at max RPM. I did cut one of the taps on the cable adapter (using pair of flush/side cutters), with a pair of flush/side cutters. This is due to HP's preparatory fan connectors. However, everything else is 'like for like'. If you're using an HP Z-System, I strongly recommend it. (Also you don't need to google 'Can I use PWM fans on my HP Z...' Yes. Yes, you can)

Just about silent at low RPMs and provides great thermals. I have this running as rear intake and I'm happy I went with this choice.

good fan
