The NZXT Kraken Elite 360mm AIO is perfect for my all-white build—the LCD display is crisp, the RGB fans look amazing, and most importantly, it keeps my CPU temps low. The pump runs quietly, and installation was smooth. The NZXT CAM app makes it super easy to customize the display and fan settings. Great performance, sleek design, and user-friendly software—definitely worth it! ⭐⭐⭐⭐⭐

This is the first AIO I have purchased and it seems to be doing its job as intended. This was put in a white Hyte y60 case as it seemed to be one of the only 280mm white AIO. I was originally going to buy the last gen version of this cooler, but figured I might as well buy this new one which just got released. Glad I did too as the larger screen is much nicer to look at. All of my opinions here are based on the out of the box behavior of the cooler, no NZXT cam configuring was done. Performance: Cools my 7900x pretty decently. According to the cooler screen, it sits around 33-34 idling and the highest I've seen it hit is 37 degrees when doing short intense computations. Installation: Really straight forward with an AMD x670e board. Way better than my previous experience installing a BeQuiet! Dark rock pro 3/4 to an intel based system. It's also great that the cooler can be oriented at different angles (30 degree steps I believe) which gives it even more flexibility in installations. (the default orientation has the tubes coming out the bottom of the screen/coldplate. Rotating the screens image requires software) Noise: Runs quiet enough. I can somewhat hear the whoosh of the fans, however it is over powered by the stock fans my case came in. As for pump noise, I'm not entirely sure I hear it. Occasionally I hear a sound from my PC, but I have yet to determine if it is coil whine from my new build, or if it is the pump occasionally whirring. Fans: I plan on upgrading the fans at a later date with lian li infinity fans, but I have honestly been pleasantly surprised by how well the rgb looks. However, I would have preferred being able to buy the cooler without the fans and fan hub included. If I wanted NZXT fans, I would get NZXT. Let me make the choice and save money by not having to buy stuff I am not going to use. Linux software support: One gripe I have is that there is no official software support in linux. But I guess I can't complain too much as I am probably 1 of 3 people that it matters to. Still, I'd like to see companies like NZXT support projects such as openrgb and coolero/liquidctl. [Rant: Even if I ran windows, god forbid I install bloatware like NZXT cam + a million other rgb software to suck up my hardware resources. I just don't get why so much money is spent on software no one likes when NZXT could just spend a day giving the open source community the usb com specs for the cooler and reap the benefits of 'free' work.] Thankfully by default the leds on the fan are white, and the temperature on the screen is also colored white. One of these days when i have hours to waste, I will try fooling around with liquidctl and see if I can get the experimental controls to work. Conclusion: It's a high end, white, 280mm AIO with a big ol' screen. And its price reflects that. It looks great and the install is easy. If you are going to blow money on a high end AIO, its going to be pretty hard to beat this one. I really only have issues on the software side.

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.

The NZXT Kraken 240 AIO cooler delivers excellent cooling performance with a sleek design. Its RGB-infused pump head adds style, while the dual 120mm fans provide efficient thermal management. Quiet operation and easy installation make it a solid choice for mid-range builds.
