Noctua NF-A9x14 HS-PWM chromax.Black.swap, Premium Quiet Slim Fan, 4-Pin (92x14mm, Black)

I didn't always pay -that- much attention to what fans I used. Most of the time, I'd rescue them out of retired builds and cases, and recycle them into new systems as a sort of "tribute" to the predecessor. When I set out to build my Skyreach PC, which was my console-killer wet dream, I knew each part going in needed to be the best possible in it's class. I initially bought the NH-L9i in Chromax Black and was so impressed by it, I decided to go full Noctua in this system. I replaced the GPU fans (noisy, kinda whiny and frankly too tall to fit) with these fans, and it's been great.I was actually surprised at how well they performed at low-speeds in tasks where noise was a concern. That said, they can get LOUD. ASUS Fan Xpert allows you to crank all connected fans to max speed and this little box becomes a jet engine. Add to that the vortexing issue with this case and things became unbearable. However, flipping the fans worked splendidly (from push to pull) and the avg temp jumped only 5c. With a mild undervolt and some fine-tuning, I had a quiet, high pressure fan that did a decent enough job repelling dust and keeping components cool.In comparison to other fans I have used over the years, I find the pitch and tone of the fan sound to be more pleasant to the ear. You'll find that most fans don't have -that- much different fanning abilities from their immediate competition, but you will HEAR the difference. I do prefer these greatly.The added bonus? No more puke brown, although I do have a slight fondness for that hilariously-outdated color scheme. I imagine the brand recognition factor is also there. And in the RGB era, seeing a brand stand up against competition without the pretty lights to mask any quality defects is refreshing and inspiring.If I had to gripe about one thing it'd be the price. You pay a -little- more than you would from competitors but honestly, you get something truly special with this company. Quality European engineering at it's best.All in all, these are incredibly well-engineered fans with the pedigree to boot. I will be using Noctuas in future situations that require low-noise, high static pressure fans. These are great. And they're kinda blingy, in their own cool way. Definitely a quiet flex.

Replaced the pull fan on my push-pull CPU cooler. It's half the width of the fan it replaced, but it weighs nearly twice as much so I reckon it has more power and I can feel the exhaust on the back of the computer has increased even though this fan only blows towards the exhaust fan. It seems to be quieter, but the fan it replaced was becoming deafening so it is difficult to compare. Appreciate the all-black color without RGB lighting.

These are great fans if you want to black out your build without sacrificing performance. I bought two and swapped them onto my Alpenfohn Ventirad and 750W PSU. Temps dropped and the slim form factor fits SSF cases perfectly. Solid upgrade for both airflow and aesthetics.

Got these to replace some fans that came with my NAS enclosure. After installing some adapters on the backplane, the provided fans were just slightly too big and the back panel wouldn't fit without some uncomfortable pressure.Got these and replaced the factory fans. I love that the power connector is so short! I already had cables running to the area and didn't need to zip tie up any slack.Airflow is the same, but these are easily half the thickness. System is super quiet. Love the black color of these. I know noctua is good quality, though the beige and brown they usually do is pretty awful for my tastes. The colored anti-vibration pads are fine. I just used the black ones because I'm basic.

Love this brand. Perfectly quiet and easy install. Highly recommended.

It’s great for CPU cooler fan replacements and looks great in black, nuff said

The slim version of Noctua fans aren't the best, simply due to producing more noise than its other products. As I read around about sizes and slim fans, I'm afraid Noctua's version of a slim fan isn't as quiet as it's sibling products, especially at higher speeds. I swapped this out with an Arctic 92mm for better exhaust performance, which the Noctua succeeds in, but noise is higher. The trade off between the two was air flow for noise, that's as best as I can describe it. I possess other brands of quiet fans; ASUS, Corsair, and Arctic are all non-RGB for the sole purpose of air pressure and I believe they are doing just as good as this Noctua 92mm, but quieter.In the end, it can be due to its 'slim' factor, as I read around that regular 92mm sizable fans will be better in noise and pressure, this one is definitely quiet at idle performance but not at higher speeds.As for value, the entire kit it comes with is actually very nice so I won't fault for quality and presentation, Noctua never fails at this. I simply had higher demands for this product and I will be searching for non-slim fans in the future.

Great replacement for any 92mm fan. Cooled the thermalright axp90-x47 like a charm. Didn’t have the same max speed as oem fan on cooler, but the noise profile of the noctua is just more pleasant, it’s hard to describe it but it just sounds better and cools the same if not better. It won’t ever happen, but there’s so many other brands that are catching up to noctua’s build quality and performance, so I hope the competition can bring some of these prices down a bit. But I get it, you get what you pay for and the warranty and pedigree of noctua is top notch. Minor gripe, I didn’t like how there’s adhesive colored rubber pads that I had to install, I get the customization aspect, but if one build I want it black the next build I want red, if I ever want to revert back to black pads, I can’t because it’s not a reusable pad.
