Love it
Love the Noctua fan—it fits perfectly on my CPU and is as silent as a deadly fart. I especially love the design, and the metal sticker it came with adds a nice touch to the style of my case. Brilliant fan, Noctua.

Works well 🤷♂️
Background I am a pc amateur when it comes to building. However installation was very simple and straight forward. As long as you do the research to find out if the screws and sections matches/fits to the board then it’s all straight forward. Has held out very well for over 2 years +, size is good and can attach two medium sized fans on each side, one for intake, one for out. Has kept my CPU, significantly cooler when using one fan attached with intake on the side. Compared to stock cooler. Maybe 5-12 degrees cooler.

Perfect Cooler for a small case!
I love Noctua. I got this at the recommendation of DanKamYouKnow. As The title says, I have an Omen and these are Notorious for their Hellishly High Heat. I can say this will keep Your Omen cool with a Couple more Noctua fans. This was easy to install, Its very Quiet compared to the stock Air cooler that come with the Omen 25L This Air Cooler will definitely do the Job, my Omen would run around 69°C ish Idling, now it sits around 53°C. The Highest Temp I got during a stress Test was 65°C, where before it would cap out at 79°C in the 2 minute Stress Test

Excellent upgrade for my needs
I purchased the Noctua NH-U9S to replace the stock AMD CPU cooler that came with my 5600x CPU. Having recently upgraded some components in my PC I noticed that the temperature on the 5600x was rising into the 90’s with the stock cooler being unable to keep these temps down. I have a ROG Strix X570-I motherboard which is a small board, therefore leaving me with limited CPU cooler upgrade options. Having competed some research I went for the Noctua NH-U9S and I am pleased to say it made an immediate impact reducing temperatures at peak performance by around 15 degrees. The instructions provided were very easy to follow - I am very inexperienced but managed to replacement the coolers just fine. The whole process took around 15 mins. I have gone for the single fan option but included are extra fittings for a second cooler fan if you wanted one (fan sold separately). The NH-U9S looks great, I love the black. Noise wise it’s not loud at all. I would highly recommend this tower cooler to anyone wanting to upgrade from a stock CPU cooler but is struggling to find the space for a liquid cooler or large sized device. Price reflects the quality and build. If you find this in a sale then it’s a bargain! This will function with both AMD and Intel CPUs and comes with the appropriate connections and brackets required.

Fantastic option if you're looking for a stock fan replacement.
This came highly recommended by various people to me and whilst I was skeptical about it at first thinking I would see a 3-5 degree celcious difference with my I7 12700F. I was blown away when I saw temperature improvements upwards of up to 30 celcious under load. I used to run 40-60 idle and upwards to 100 celcious under load but now after testing this product with my CPU under load for a few hours it sat happily in the 60s occasionally dipping into the 70s. I've never spent this much on a CPU cooler before but I can gladly say that this product was well worth the price. If you're running stock your CPU will thank you if replace it with this.

Not the biggest, but easy to fit.
I brought this for a new build PC when the cooler I had bought (Be Quiet Dark Rock Pro 5) wouldn't actually fit onto my mobo. It came the next day and fitting was really easy. I ran some benchmarks to test my new build and whilst the top of the new Noctua cooler became warm it was not hot (and that was after running the processor flat out for 10 minutes a couple of times) so it seems to work well. It's not as impressive in size as the Be Quiet cooler, but performs fine in my non-overclocked PC.

It does the job great
Replaced the pre installed fan for intel I-7 1400 in my gaming desktop and went down from 65-72 degrees on idle and 85 to 94 on full throttle to 45-50 idle and 65 to 70 maxed. Great option if you looking for more reasonable temperatures !

Did not receive 1700 socket adapter
The cooler is great for it's size. I'm using mine to cool an I7-12700. One of the reasons I bought it though was because the product page repeats over and over that it is compatible with my LGA 1700 socket, mine did not come with the right bracket however. Of course Noctua are renown for their customer service and state of their website that they will send out updated mounting brackets if you ask for them, but it can take 20 days. After sending a moaning email to them they agreed to send my mounting bracket with express delivery at their expense and I got it shipped from Austria within a couple of days. This is great and all, but I really wish they didn't lie to me on their product page.

Super Kühler!!! Ich hatte bei meinem Acer Predator Orion 3000 beim zocken wie zb 7 Day to die, immer 90grad und er hat die Leistung reduziert, mit dem Kühler bin ich bei 66-67 grad, einfach der Wahnsinn!

Very good cooler. It lowered the CPU temperature by about 20 degrees (i7 14700 KF). It is a fairly quiet cooler. I had to buy extra screws to install it.

Excelente solución para enfriar el CPU y cabe perfectamente en casi cualquier gabinete (excepto gabinetes tipo "slim") Yo lo instalé con un CPU Ryzen 5 5600X y puedo decir que es mucho mas eficiente que un enfriamiento líquido de 120mm además de ser increíblemente silencioso

tyyyyyst och kyler mycket bättre än orginal kylare

Al principio tenía algo de dudas sobre la funcionalidad tan maravillosa del disipador. Lo puse en un Acer predator orion 3000. Elegí este porque es de los pocos que caben en esta torre tan pequeña. El pc está muy bien en general pero venía flojo de refrigeración de fábrica, aunque con cooler máster. En cualquier cosa algo más exigente se ponía el procesador a 89-90°, eso es una barbaridad, rozando el límite ya. Después de poner noctua, desde el primer momento, los mismos programas y juegos de antes, mismas características, 25-30° menos que antes, de momento (3 días) ha llegado máximo a 65 °. Eso es la ostia de bajada de temperatura. Me sorprendí para bien, pero que vamos. Esperaba alguna mejora pero tanto ni imaginaba. Y luego el montaje super fácil. Ni siquiera fue necesario desmontar la placa de Acer. Fue desmontar el viejo, mirar las partes que venían para mí placa (1200lga en mi caso, pero ahí partes y para otros - 1700lx, amd, etc...) y probé 2-3 variantes de montaje sin quitar la placa y colocar el soporte que viene en la caja de atras. Total, en 5 min aprovechando el soporte de fábrica coloque las placas y tornillos necesarios para sujetar el disipador, un poco de pasta térmica después de limpiar el procesador de la vieja (ah, dentro de la caja viene una jeringuilla con pata térmica de la marca noctua, solo eso vale 10 euros, así que un detallazo!), apretar las dos tuercas con muelles para que reparten la pasta y se unan bien el radiador con el procesador, colocar el ventilador y enchufarlo y au. A funcionar. La verdad que una maravilla.
