The cooler works great and is quiet. I have some strange interactions with some other software that monitors or manages my fans and Temps, so the software aspect wasn't as easy as it could be. The fans don't mark airflow direction, so I had to look that up. Surprisingly it didn't fit that well in my case with the radiator tubes down. It is slightly anlged with some bending of metal. I'll chalk that up to a problem with my case though. People should look at clearsnces before buying though. Overall, the cooler itself is great.

This NZXT cooler is great, it keeps my temps low compared to my air cooler i had previously. Installation was simple and quick

Cooling is very good. Looks very nice. Recommend for high end cpus.

Very easy to install and has been keeping my temps very low with little noise!

I replace an older 120mm AIO systen on a Ryzen 2600 that was running idle at 44c and high 90c under load to 30c idle to no more than 63c under load. The only drawback is this takes up some room so make sure your case is prepared for a 280mm radiator. The install however for mounting was easy ecen though the instructions weren't the best.

Awesome cooler for my AMD 5 5600x !!!!!! Went down frim 63C to 53C IDLE. Very quiet and you can change colors of background amd the nzxt logo. I got in open box and saved some dough that way!!! Pretty simple to install but barly fit my case !!!!! I had to move cables around but i got it to work ! Make sire to measure measure measure !!!

Keeps my i7 12700k nice and cool! Easy install and software for the rgb is user friendly

Keeps my cpu bery nice and cool with no issues and super easy to install

NZXT AIOs have been a popular cooler for quite a long time. If you watch any PC build videos it is very common to see one of their coolers being used. They offer consistent quality and look very good. However, they also come with some complaints. One is the fans are reported to be louder than they need to be. I like many users didn't use the supplied fans so I am not able to comment directly on the fans supplied with my cooler. I already had some ARGB fans from a prior build and I elected to use them. The CAM software is also often sighted as a problem. I am using the CAM software and I can report you are not required to use it but if you want to change the cooler colors it is a must. I also just created a guest account so it wasn't really a problem and it does add to the functions of the cooler. I chose the NZXT cooler because I built in a micro ATX chassis and this cooler was reported to fit correctly. Also, I was able to get it from Best Buy so that is always a plus since I knew they would refund it if it didn't fit. Overall, I am very satisfied with the performance of the cooler and it does look great. The purchase process with Best Buy was very easy and it was shipped a day faster than expected. I could not find this X63 version of this cooler in stock from major store and was very glad when it came up in a search at Best Buy.

I would give this a 3.5, but a 4 for its easy installation. This barley fit in my NZXT H510 case. The cooling is great, however using NZXT CAM software isnt great. The fan noise is really loud just using the CAM software. If it wasn't for the easy installation this would've easily been a 3-3.5 due to the CAM software.

Overall decent cooler and very easy to install. Pretty quiet in my opinion.

I installed this big guy on a Nzxt h510 case., believe it or not and I needed some tutorial from YouTube but it was totally worth. It works over the expectations, keeping my cpu ' s temperature way below 36 Celsius which is the most common standard while idling. I don't use stressing testing apps but on full load I can't remember one single time over 75 Celsius. The fans are pretty good but if you want extra silence be ready to spend more cash (much more) and go with Noctua. Not worth, since they are quiet enough and due to the very low temperatures you can afford to play more with the setting and set up an higher limit for the fans spin. Overall, a great purchased, even because it was a little bit discounted at the time of purchase and some reward that I could use did the trick.

Paired this cooler with a Asus Z690 Tuf DDR5 motherboard and a Intel I7-12700K and with just a basic AI overclock by Asus running around 5.0 GHZ this cooler has the CPU running in the 20s at idle and low 30s at load (everyday use, not gaming). Outstanding cooler

This was my first all-in-one cooling system, and it was relatively straightforward to install. It includes thermal paste on the unit. I had to correct was making sure both fan cables were oriented so that they could reach the mobo for power. Addtionally, I had to rotate the tubes running to the radiator to orient them in a way that wouldn't interfere with components and didn't seem unsightly. It's pretty easy to figure out. I didn't feel like springing the extra money to get the display for temps, and I'm not sure I really care. It seems to keep my Ryzen 5 5600X pretty cool even under high load. Probably not as good as their top of the line coolers, but good enough.

The Kraken is the best best cooling system I have ever had. I have absolutely no problem with it. It runs a steady 40 Celsius. It runs smooth, fast start up and no overheating issues. Will purchase NZXT products again.

Keeps my overclocked Ryzen 5 5600x in check. At 100% cpu load, it keeps temps at around 65-70 degrees with a 5.9gig over clock. Alittle over priced

Very good and quiet liquid cooler. It's a bit spendy but I have an nzxt case so it was a perfect fit. Much quieter than my last cooler master cpu fan. Made a custom cooling profile with nzxt cam software and it's working well and keeping my ryzen cpu around 50 degrees under gaming loads. The cooler has thermal paste pre applied but if you're not careful you'll get bubbles in there which aren't ideal. It won't overheat or anything but I did clean it off and replace it with my own thermal paste and that shaved a few degrees off cpu temps all around. Heads up, the pump is a bit loud when you first install but after it gets going it gets quieter so give it about 20 minutes for it to break in. Now it's whisper quiet.

Very good performance, looks good, but had ram clearance issues with corsair vengeance rgb pro ram inside of corsair 4000x, with an atx motherboard. The fans aren't necessarily the best performing, but they perform within 1-3°C whem compared to better fans, like Noctua's.

It works perfectly! It really helps keep my computer cooled and working at top performance. I highly recommend this product.

Bought this open box for the first PC I've put together. Easy install, has worked great for months and looks really nice. Great addition to you computer.
