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 25LThis 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

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 !

Small and deadly!
I got this because I upgraded cpu from a ryzen 7 3700x to a ryzen 7 5800x3d. The new processor is an absolute beast but its a thermal nightmare. I had a wraith prism installed but the cpu temps were going over 90 degrees Celsius... So I needed a new cooler. I'm limited for space so this does the job perfectly. The instructions were clear and very easy to understand. You can also buy an additional fan for this unit if you have the space. I went from over 90 degrees to around 75 under load. I'm going to add another fan so this will come down another 5 degrees I'd say. Oh and the fan is very quiet too, and looks sleek and refined.

Excellent upgrade for my needs
The media could not be loaded. 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.

Great quality!
Great quality item, easy to install and does exactly what it says on the tin! Reduced the running temp of my sons gaming PC by nearly 30 degrees.

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.
