After installation, the fan monitoring app would show that my system was overheating. After the usual system checks and reading everything I could find online, I contacted support. Tech support walked me through some procedures and said that if it does not fix the problem to return for replacement. So I reset all connections including the CPU paste and monitored again. It still overheated and I asked NZXT for a replacement. It arrived next day. I removed the faulty cooler and in the process discovered that the pump's cable was not securely connected. It was my fault.

I could blame the poorly crafted printed installation instructions because, they really made a mess of that. But really, I didn't double-check the pump's power cable connection. Other than that, installation is quite easy. From box opening to computer start-up, 10-15 minutes at a meditative pace. Double-check power connections.

This cooling system is the most quiet I have ever used. I cannot hear the fans nor the pump unless I open the running computer in a completely silent room. And even then, I have to press my ear right up to the case.

I'm impressed so I give it highest the highest rating.

Very Efficient Cooler

Reviewed in the United States on December 8, 2020

Color: BlackSize: Kraken M22Style: M22 120mmPattern Name: CoolerVerified Purchase

I must say that this cooler is something every person with a gaming build should have. It's inexpensive, and effective, not to mention that it's compact and looks pretty good. I was a bonehead and installed mine upside down, so now my NZXT logo now reads more like ┴XZN, which has become a running joke among my friend group. Air bubbles have arrived as well due to this folly, but I don't mind hearing the sound of Windex sprayers every couple of minutes.
Now, to get serious, the cooler does exactly what it should do. I have my computer running for hours on-end, usually playing fairly high-end games or running multiple demanding programs (You'd be surprised how much power GIS programs need...). The maximum temperature my CPU ever reaches is 56 degrees, which is only for a few seconds before dropping back down to around 50-52 degrees. For such a compact unit, this is very satisfying. If you want to keep your PC running nice and cool, which is always great for preserving the hardware and keeping your fans from running at full RPMs the entire time the machine is on, this is a perfect addition. Will be looking at a beefier NZXT-brand cooler once I upgrade motherboards and CPUs to something more demanding.

Didn't last a year before the pump started making noise.

Reviewed in the United States on May 20, 2022

It was properly installed, The PC was moderately used a few hours a day. At about 10 months in the pump started making noise and CPU temperatures went to 50c at idle. I had no choice but to replace it. I'm not a fan of making bad reviews but this AIO is not worth the money or the time to install and then replace a few months later. I will give it the benefit of the dought that I may have just gotten a faulty product. If you have bought one of these I hope you had better luck than I did.

CAM software killed my machine - will NEVER buy another NZXT product.

Reviewed in the United States on April 5, 2020

Color: BlackSize: Kraken M22Style: M22 120mmPattern Name: CoolerVerified Purchase

I'm so pissed right now because I can't even return the product because I had to modify the backplate to cut off the Intel arms. Bottom line, built a new AMD 3950x rig to replace my current system. Everything went fine for the most part, nothing I couldn't handle, and got it loaded and installed all my software I needed and benchmarked the system. Everything was working beautifully for days. I was just about to pull my video card and a couple SSD's out of my existing system and install them in my new rig and I remembered I hadn't installed NZXT's CAM software. Wasn't really important since it can't control the pump, only the LED's. So I downloaded latest version and went to install it.

WORST IDEA EVER. It locked the computer up during the install. I had to hard restart it. CAM was there, however. So Windows 10 somehow finished the install. I went into it and set colors I wanted and exited out of it. This led to my display glitching and my computer hard resetting. It took 7 tries to get Windows to stay up long enough to uninstall the software, but the damage was done. I'm an expert with computers and even I was shocked at how screwed up my computer was with random reboots and glitches - WHEN I COULD get into Windows.

I had to reload from scratch. A week of work wasted. Thank god I hadn't pulled my video card and data SSD's out of my current rig. The sad thing is, google it and this is seemingly a very common issue.

Good for HTPC use

Reviewed in the United States on April 10, 2020

Color: BlackSize: Kraken M22Style: M22 120mmPattern Name: CoolerVerified Purchase

UPDATE: Forgot to mention in the original review but due to high spikes in voltage on the Ryzen platform ( X570 and 3700X) the temperature will spike into the mid and sometimes high 70's but the average temperature does stay in the 50's. After extended heavy gaming use, sometimes it will also reach lower 60's. Also the pump is built into the radiator reducing cooling capacity. But hey, the cooler looks good and the pump is quiet (unlike the included fan) so once you change the fan to a better one it's not bad at all. Maybe just a bit on the warm side.

Got this to go into a new HTPC build since air coolers don't fit in the Phanteks Evolv Shift. It works for cooling my Ryzen 5 2600X but there are temperature spikes that this cooler can't do anything about. But overall, it does keep the average temperature down and keep it from overheating. Also fits well in my case. I do want to note that the fan that is included is very loud when when it start ramping up so I would highly recommend setting a custom fan curve.

Great if it add a second fan and great thermal paste

Reviewed in the United States on July 19, 2018

Color: BlackSize: Kraken M22Style: M22 120mmPattern Name: CoolerVerified Purchase

I'm using the phanteks evolve shift and it looks amazing in it.
Pros: looks amazing, cools very well (ryzen 7 2700x with limited airflow) To get those good temps I added a corsair higher end fan to the radiator to get a push pull config and I used the top end thermal paste. That's how I maximized its cooling potential. It would probably run even cooler if you have better air flow trust me my case has super limited airflow.
Temps: at idle 35 to 45 while gaming hit 60 but mostly in the 50s. The kraken m22 surprised me. I can actually hit 4.2mghz at upper 70s which I know the 2700x is cable of 4.3 but for this little dude to do that it gets an A in my books.

Cons: installation you must install pump head to motherboard before putting motherboard in case! Put down the antistaic bag and put motherboard on top apply alot of pressure for the screws and ur good. Dont be afraid to put the needed pressure. I honestly was afraid I might have killed my cpu/mobo with how much pressure was needed.

Works like any other AiO

Reviewed in the United States on October 21, 2019

Color: BlackSize: Kraken M22Style: M22 120mmPattern Name: CoolerVerified Purchase

This AiO is pretty decent. I tested it on a i7-8700 (unlocked) and compared it with a tower cooler I got from cooler master. (instead of using the fan it came with, I'm using two Noctua redux fans) It was simple to install and I noticed that it really cools my CPU well. I attached it to the front of my case on the top fan mount. The obvious difference I noticed is that my PC is quieter compared to how it was with the tower cooler, the temps also are at 62C and below while playing games. Even though they have the pump in the center of the radiator, performance does not seem to be that hindered. It works like any other AiO. I would recommend this cooler.

Works great until it doesn't work anymore

Color: BlackSize: Kraken M22Style: M22 120mmPattern Name: CoolerVerified Purchase

I liked this product for cooling my CPU but even after trying various troubleshooting methods for it, the pump no longer functions properly and the only way I can get it to cool my CPU is if I unmount the radiator and smack my hand on it, and as soon as I stop, the pump stops working properly and it gets loud and the temp increases about 40°C. I dented the side of it while trying different troubleshooting methods so I have not even bothered trying to hit up NZXT because I’m guessing it would void my warranty. I purchased a Kraken x53 and it will be here soon so I look forward to trying that instead.

Cumbersome Installation, Loud Fan.

Reviewed in the United States on November 11, 2019

Color: BlackSize: Kraken M22Style: M22 120mmPattern Name: CoolerVerified Purchase

So my experience is kind of mixed here, to get started let me say that once you get it install it will do it's job admirably ( with some details you need to be aware)...My idle temperature on Ryzen 3600x is 32* now the CPU wont ever ever hit 60* no matter the stress but that comes at a price...OMG what a noisy fan. on the manual if you read it NZXT will tell you to keep it at MAX ..that is insane my fan RPM is on idle 1700rpm and i'm not sure this is right or wrong. Second big issue is the installation and overall design of the product. NXZT how come you provide this extremely cheap "univerzal Backplate" made of i have no idea what material it's so fragile that to think this will be holding your precious infinity glass cooler made me tremble ( please install with caution) Do not over tighten anything for your own sake. And then we go to a minor detail but still bothers me...who came out with the idea of the mini USB placement on the AIO???? WAO totally kills the magic of the amazing effects you will get on your Cooler....top of the line. DONT listen to reviews talking crap about CAM it is in my opinion an amazing software that really keep an eye on every details it even let you save profiles with diff combinations of RGB just make sure you go into Privacy and uncheck the data collection thats it. One thing that really got me is the lack of RGB FAN, NZXT how come you did not include an RGb FAn on this it's like it's on purpose cuz i dont even know what fan i can use on the radiator to be able to have RGB since all your other products need the controller HUE +..

The instructions aren't written very clearly

Reviewed in the United States on December 13, 2023

Color: BlackSize: Kraken M22Style: M22 120mmPattern Name: CoolerVerified Purchase

My old NZXT radiator pump died. So, I used the warranty to get a replacement. The replacement was this one. After installing it, I plugged it into my motherboard, and the light on the top flickered a few times and then went out. On its way out, it took out all of the LED lighting connected to my motherboard. So, my motherboard still functions; but, after several hours of troubleshooting and work, only one motherboard-connected RGB works (and only in Blue and green - no red). The light on the top of the processor part of the cooler has never come back on.

I'm also unimpressed that it uses USB-type connections but isn't recognized by its own app. I called customer support and they told me it's normal for the app to not recognize its own hardware. I thought NZXT coolers looked cool - but have since been disenchanted with their product. I will likely purchase another brand next time.
