Easy installation, keeps CPU cool and has great asthetics. Wires are pretty easy to connect and find, and NZXT Cam makes it seamless to customize LCD screen.

Absolutely love the look of this thing. Nzxt Cam works great to control fan speed and making sure the radiator gets good air flow. Very easy to install if you just follow the directions. good airflow in your case keeps noise levels down. all cables are of good length and were easy to install. Keeps my R7 7800X3D cool at 82° while running cinebench.

This is a great CPU cooler. It keeps my CPU much cooler than the air cooler I had before. It also fits in my mini-itx case, which is a huge win. The set up was pretty simple and the paper instructions ensured that I didn't make any mistakes. However, the fan connectors do not work on my system, after researching, I found to be a common problem. What I mean is that there is a cable that can fit three fans included in this AIO, but with the two fans included, when plugged into my sys_fan plug on my GIGABYTE Z590I AORUS motherboard, the connector cable does not power the fans enough. The fix to this was to not use this cable and instead plug in the fans separately. This works, but I had to buy a separate fan splitter for my other fans. A little annoying, but not the end of the world.

I've only had mine up for a short time now, installed on a B650 Gigabyte Aorus Elite AX motherboard with a 7800x3D in an NZXT H6 Flow case, but it's been perfect for what I wanted. The AIO itself is probably overkill for a 7800x3D, so if you're strictly looking to cool your fancy shmancy new processor you don't have to spend this much to do it. Go for a Thermalright Phantom Spirit or something inexpensive; this is only really necessary if you want the aesthetic that it provides. Since I live in an old house with no AC, an AIO can be a nice help in the hot summer months and the ease of airflow in and out of the case makes keeping the entire system relatively cool a lot easier, but still... it's a premium price for the look you want more than the functionality. This AIO does include brackets for AM4, AM5, and for Intel LGA1700 installs, and it's deceptively easy to install; the instructions aren't particularly clear, and I've normally just stuck with air cooling in the past so this was a new one for me. Since I installed it on AM5, it was just a matter of removing the plastic CPU brackets on the motherboard and then screwing in the dual-post screws (long side toward motherboard, instructions are unclear on this) with the AIO's included plastic brackets for each facing in the indicated way for AM5. The metal bracket on the CPU cooler twists off easily, and you can then just replace it with the version you need if the pre-installed bracket wasn't what you wanted. Thermal paste is pre-applied to the cooler, and the pipes from the cooler to the radiator are flexible enough to be adjusted to however you need them to be. And that's pretty much it, just screw it on with the provided thumb screws and you're done. Watching an install video can help if you're a first timer or uncomfortable with the process, but it's much easier than it appears at first glance and was much more simple than dealing with some of the annoying backplate support designs that some air coolers have. The NZXT CAM software has been easy to use and has plenty of useful information on it, you can rotate and customize the display of the CPU cooler to show what you want (I use GPU/CPU temp information on mine, looks nice and functionally useful). No complaints about the software at all, sometimes that sort of thing can be futzy to deal with but this was very simple to set up and understand how to use. Overall, it's outstanding. The install was easy, the fans aren't silent but aren't any louder than my case fans, it keeps everything very cool even on a warm day.... couldn't ask for much more. If something like this looks cool to you for the build you're doing and you can afford the price difference over air cooling, I can't imagine anyone being unhappy with this one.

This is a great little AIO, I did not think I needed the Elite model, the lager elite display is nice but my PC is hidden behind a triple monitor sim rig, so didn't care about the larger elite screen. Easy install thanks to youtuber Mr Matt Lee, thank you sir. I'm no expert and I'm sure the supplied fans and thermal paste work juts fine. Because this was my first build in a long time using high-end cpu and gpu, I changed both out. I wiped off the included thermal past and applied some Noctua NT-H1 3.5g, Pro-Grade Thermal Compound Paste with a spreader to the i9 cpu directly. Who knows if that is truly better but for the cost of the paste and the time it took why not. I swapped out the supplied fans with 3 ASUS ROG Strix XF120 Whisper-Quiet that were on sale and used the supplied fans as case fans. The original fans should/would have worked fine, I picked up the Asus fans as case fans originally, but decided they seemed better quality (i'm no expert) so I swapped them I also used a Thermalright Intel 12th/13th Generation LGA1700 Anti-Bending Buckle, instead of the default cpu chip holder. This supposedly gives better even thermal coverage, preventing motherboard flex, the idea is sound and for the cost, why not. As this was a new build I have no before and after numbers. Software is a simple install and you can change display and temp read outs, here in the USA we use anything other than metric system so Fahrenheit or elephant ear flap speed makes more sense than Celsius. All in all very please works fine, keeps the temperature low, I do have a great case with great airflow with 9 fans including the 3 fans in the AIO. Highly recormend.
