This cooler is definitely a beast. It keeps my Intel Core Ultra 7 265K running cool, and I’ve never ever heard the fans ramp up to full speed—even when stressing the processor. It’s probably overkill for my setup, but the performance and quiet operation are excellent.

★★★★★The King of Air Coolers retains its Crown.
This has to be hands down the greatest air cooler ever made.
I am using this on a Core Ultra 9 285k, and under load my CPU rarely passes 50c. I was using the previous Noctua Tower Cooler(Noctua NH-D15). Setup and instructions are extremely easy to follow and simple to install. They made some changes to the screws, but the overall setup remains the same.
Like the previous model, this cooler is quite huge - it's around 15% bigger than their previous generation, and it has a ton more heat pipes. This is almost equal to an AIO in cooling performance. In fact, I think it's even better.
The real major downside to this cooler, is cost. There are AIOs that are cheaper than the NH-D15 Gen2, but what you get is unbeatable. Not recommended for low power CPUs (i3/i5. Non overclockable CPUs, etc.).

★★★★★Sufficient to keep Intel Core Ultra 9 285 at stable 80-81 C at full CPU load
I installed this Noctua air cooler in my new PC build, which includes MSI Z890 Tomahawk motherboard and Intel Core Ultra 9 285K processor. I initially thought I would need a water cooler to meet the 250W which my CPU can easily generate, and was hesitant because I had some doubts about longevity and long term reliability of water cooling. Of course, gamers who upgrade their PCs regularly probably upgrade their watercoolers too, but in my case I wanted a PC which I can use for at least 8 years with minimal maintenance. I was very happy to find out that this Noctua cooler can handle that amount of heat. There was a concern about enough clearance for DRAM; I got one of the slimmest DRAM modules on the market, Crucial Pro DDR5 RAM 64GB Kit (2x32GB) 6400MHz CL40, but even that DRAM was a little taller (34-35 mm) than the default clearance of 32 mm over DRAM shown in drawings of Noctua. Luckily, it is extremely easy (and approved and recommended by Noctua, if needed) to move the fan which hangs over DRAM slightly upwards on the radiator (it is held in place by wire clips, so one can take it off and install again anywhere on the radiator without tools) to create a few mm of additional clearance. In my case, this fan sticks out a little more than the fan in the middle, but there is still more than enough clearance of the cooler in Fractal Design R7 case. Since fan is bigger than the radiator, there is no reduction in cooling from its repositioning. Manual of Noctua is excellent, written in good English, good pictures, even a screwdriver is included! Very easy to install. Thermal paste included.
I am very pleased with the result. The cooler is quite. Noctua has a reputation of a long lasting brand (6 years warranty). Cooling is even better than I expected: in AIDA64 Extreme stress test at full CPU load (without overclocking), the CPU temperature is kept steadily at 80-81 C. A little more money than AIO, but no risk of pump failure or water damage. The worst that can happen is one of the fans fails, but there are two of them and massive radiator would work as a passive cooler even without fans.
Talking about water leak risk, I found FAQ on Corsair web site, they say that they see water leak failure rate of 0.016% with their sealed AIO water coolers, i.e., one out of 6250 AIO coolers will leak water-based coolant in the PC. If/when when it happens, I would imagine, liquid may kill the motherboard and/or GPU or PSU. I found no data for frequency of pump failures in AIOs, but people say that pump failures are more frequent as many saw pump failures but not water leaks. Anyhow, air cooler would not leak and fans are very reliable these days, so there is basically nothing to fail :)
Noctua has a database on their web site with compatibility of different models of their coolers with processors and motherboards, a good resource to check before buying.

★★★★★ideal cpu air cooling setup for me. does the job still 2yrs later!
some people are surprised I don't use liquid cooling but this thing a silent and effective behemoth that never gave me grief during installation or daily driving. Going strong two years later!

★★★★★Never over 43 degrees
I thought liquid cooling was the only way. Then I tried this monster out. My computer has never been this cool. I did have to bump up to a full case which is not a big deal. Also it is extremely quiet, which it's Noctua so yeah. Easy and straight forward to mount, awesome thermal paste, 10/10 would recommend
