Everything you want in a high end AIO
Essentially an EK waterblock AIO with Noctua fans on the radiator, pretty good LED screen and another fan underneath the LED screen to splash air on the motherboard. It does use ROG's Armory Crate to adjust fans and the display to anything you want. I love it. It doesn't sound like a fish tank bubbling, and every part including the ROG controller is quality made. In my personal use case I did use my Lian Li fans for easier daisy chaining over the Noctua fans which have a 3 way splitter. I did mount this in a LianCool One in which top mounting wasn't going to work with my B550 Aorus Pro motherboard so my only option was to front mount it. It is pretty beefy in terms of size with the fans I chose but as always do research in what your case can handle as you may run into space issues. CPU(R7 3700x) temps around 37°C at idle and no higher than 75°C-ish on load as far as I remember. No real benchmarks were made. Just glanced over as I was gaming. Overall: Pros: Top Quality and Performance without a custom water loop. Cons: Price but you get what you pay for in this case. Very Satisfied.

Top of the LIne Cooling
Asus is known to make the highest quality computer products, unfortunately, with this reputation, they also have the highest prices. This is a great cooler, but I honestly can't say the increased price will cool your CPU any better than many of the lower-priced units. After all these coolers are simple "machines" They move solution through the pipes, radiator, and over the CPU to take heat from the CPU and dissipate it thru the radiator. Not really that much engineering involved. The only part that is not generic is the actual pump. Some have fans built in and some, like this one, have small screens to display various things - pictures, jifs, and info, such as the CPU temperature, etc. These I like to call "bells & whistles", they contribute nothing to the unit's cooling capability. It has become just a matter of your pocketbook and wishes.

Price Premium, but Top of The Line.
I purchased this liquid cooler for my ASUS desktop build last year, and I must say it's served me quite well thus far. No complaints, aside from the software which could be a bit shoddy at times, but was able to get it working fine after a while. Temps have been nothing short of great, and with my mix of primarily other ASUS components it looks great in my build as well. Would recommend.

A great addition to a ROG build
I purchased this AIO a few months ago when I decided to remove some Lian-Li fans and AIO from my build. The old fans had started to turn off and had poor integration with AuraSync. I wanted to get a product that would work seemlessly with my Dark Hero VII motherboard, and this AIO was an excellent choice. The cooling has been great and I enjoy being able to put different pics onto the LCD screen. The screen can be orientated landscape or portrait and it comes off the top of the cooler making installation easy. It is a bit pricey, but the customization is worth it.

Great aio, but software is bad
At msrp, this aio is great. Kept my 11900k nice and cool and it can also tame my 13900k without any issues. Ended up using my lian li, and antec fans over the Noctua because I wanted rgb, but the Noctua fans that come on it are obviously amazing quality, great static pressure, and very silent. Software you need to use for the screen is Armoury Crate. When it works, it's easy to change the images, and gifs on the screen. It's bloatware though. So it always has things running in the background, and conflicts with other programs.

Excellent!
Very high end. Works great to cool 13900k. Looks great. It’s not too loud. Install was a piece of cake but instructions weren’t very good. Intuitive though if you’ve done this before. ASUS ROG quality does not dissappoint

I was very excited to get this AIO cooler for my new build. Just could not get it to work.
1 out of 5 Pros Looks good Cons HORRIBLE directions / instructions Could NOT get it to work The worst customer service I experienced in YEARS Ok.. Where should I start... I love ASUS. my current build consists of mostly ASUS products, I even have an ASUS monitor. So it was only logical I stick with the brand. Huge mistake. For the life of me I could not get this thing to work. I did everything I could. I even attached it to my current build which works effortlessly, the LED just would not turn on, the pump would not work. Parts for new build New Intel 12th Gen I9 12900 New 2TB Samsung 980 Pro SSD 2 new 16GB X2 RGB Trident DDR5 Ram 36*36*36 ASUS Riyujin 2 360 AIO Cooler New ASUS Rog THOR 1200 Watt Power supply 7 Lian Li AL120 Fans Corsair 7000D airflow case ASUS Strix 1080 TI GPU (Not new.. Current GPU I use in my current build) I assembled new build and AIO II 360 Cooler just would not power on for whatever reason. I tried EVERYTHING. The directions were HORRIBLE. The ROG Controller is a joke. I tried the ROG Controller with the cooler and the rog controller that comes with the Z690 Maximus Extreme Motherboard. Neither worked. I called ASUS, got on Online forums and still nothing. I decided to return the one I had and maybe a replacement would help. That came and the same problem existed. I got so fed up that I gave up. I returned it all. I love ASUS products but this left a very bad taste in my mouth. I could not get Cooler to work at all. Once I was able to get rig to POST it would shut down after 5 mins because the CPU wasn't getting cooled. The directions were the MOST unhelpful directions you would ever see. The customer service was 1 of the worst I ever experienced. I spent nearly 10 hours over 45 days trying to get ASUS to help me get this working and none of it worked. I haven't gave up on ASUS but I may have given up on this product. Who knows maybe I will try again but for now I wasted too much of my life trying to get this to work. Please learn from my error.

Would not recommend at all. -Whirring (When gaming) -Buzzing noises (When gaming) -Fans get loud (Even on silent) It is quiet however when in Windows. ALT TAB back into again and buzzing is audible again, almost like GPU coil whine. I would stay away from this unit and get ARCTIC Liquid Freezer II 240 instead. I am reverting back to ARCTIC Liquid Freezer II 240, which is virtually silent. The screen was very good though, going to miss that. Price is high and overpriced. ARGB connection was pain and getting the fans to properly use RGB, fan controller that comes with it doesn't properly support ARGB i believe.

Excelente funcionamiento, funciona tal cual se espera de un enframiento de 360mm manteniendo temperaturas bajas incluso a temperaturas ambiente elevadas. Su pantalla te permite mantener el control de multiples cosas o colocar imagenes al gusto.
