NZXTKraken M22 120mm - RL-KRM22-01 - AIO RGB CPU Liquid Cooler - CAM-Powered - Infinity Mirror Design - Reinforced Extended Tubing - Aer P120mm PWM Radiator Fan (Included) Black

Originally posted 8/19/2017 (May update if issues occur):I bought this cooler for the new AMD Threadripper 1950x. Matched with the Gigabyte Aorus x399 gaming 7board and G.Skill TridentZ ram, I have a great RBG themed system that looks great in my Corsair 760t case. I have been running this for about a week now, with no real issues with the cooler itself. Although this is not a TR4 specific cooler, it does indeed work well with Threadrippper.NOTE: The temperatures I am reporting on in this review are for the AMD Threadripper TR4 socket CPU. This CPU is much larger then other traditional CPUs from both AMD or Intel, and therefor the idle and full load temps I am reporting are going to be somewhat higher then what they would be on a more traditional CPU. Because of the TR4 socket's larger size, traditional AIO coolers such as this one (and others from big brands like Corsair) do not cover the entire IHS of the CPU, and because of this, they do not dissipate heat as efficiently on Threadripper as they do other traditional sized CPUs.AMD provided the bracket needed to mount this cooler to the Threqadripper TR4 socket. Pretty easy install. Running the cam software, I am seeing idle temps in 'silent mode' at about 31c to 33c (during warmer days in summer, like the time of this review, my room is a little bit warmer, so ambient temperatures can play a roll in this). At full load testing with prime95, or doing heavy video task with Vegas and Handbrake, temps will run to about 65c to 66c if the fans/pump stay in silent mode. Put them in 'performance mode' and they drop to about 62c.The cam software has been a sour topic of other reviews. I am running version 3.3.5 (the latest at the time of this writing), and I can say I am not having any real issues with it. I get great control over the pump and fan speeds, and I have no real complaints with it thus far. The only thing I had issues with, was the cloud syncing function. If you create a cam account and sign in with it, the software will monitor all your temps and upload the data to it's cloud, allowing you to downloading the mobile app and keep tab an eye on your temps via your smart phone. It does work, as I have successfully used it, but it seems hit or miss. I left my system booted up running some tests to make sure it was stable, and I was checking the temps on my phone while on to go. After a while, I assumed my system had crashed, because the cam APP told me the PC power was off, and there was no data being sent to the cloud. When i got back to my PC, both Cam and my computer where still fully up and running, but for some reason, cam quit talking to the servers, leaving my mobile app to display that my PC was powered off. Other then that, so far, the Cam software has been solid for me. It saves all my settings properly, and everything loads up the way I had it after I reboot or shut down.Overall, so far, I am happy with this cooler. If there are any issues in the coming days, I'll be sure to come back and update this review.NOTE: For those of you looking to buy this cooler for certain boards, including the Gigabyte Aorus x399 Gaming 7 board that I used, there is ram clearance issue. Be sure to research your board's specs and decide of this is going to be an issue. If you are picky about how your builds look, you might want to investigate your board's spacing between the CPU socket and ram slots, as you may have to rotate the pump to make it fit on your build, making the 'NZXT' logo no display properly. On the Gigabyte X399 Aorus gaming 7 specifically, the pump WILL block the first ram slot on the right side, especially if you have tall heat spreader ram like I do with the G.Skill Trident Z ram. On the Gigabyte X300 Aorus Gaming 7 board I am using,this is only an issue if you are only using 6 or 8 sticks of ram, as the other number of ram configurations (1,2,3 and 4 sticks) do not require you to use the first slot.

Edit again: 3 stars added back for excellent customer support. The RMA process was quick and painless, and here I am enjoying beautiful RGB and moderately okay cooling performance all over again.Edit: Took off 3 stars for dying after 6 months. I sent a ticket to NZXT asking if they'll be able to RMA it, but considering I got it from Amazon, I'm probably out of luck given I didn't purchase the one dollar's worth of insurance for two years. Why does that got to be a separate thing I have to click, Amazon? You've just costed me 180 bucks (because I ordered this for one-day shipping). I realize my issue is partly with Amazon's, but it's also with NZXT whose product failed after a relatively short period of time. Regardless, rating may change depending on my experience with the RMA.Brought my temps down on my Ryzen 1700 about 5-10 degrees. Mine idles at about 38 degrees, on full gaming and streaming load about 50-55, and on 100% CPU load it cruises at 75 degrees. I have it overclocked to 3.7 at 1.225v thereabouts. I live in Southern California so my idles are never going to get super low, but for a 5-10 degree difference versus the stock AMD Wraith Spire (which I suppose the reviewers suggest punches above its weight), I sort of regret paying a billion dollars for this.On the one hand, it does look super pretty and I've always been a style over function kind of guy, so I'm keeping it. I wish there was enough clearance to fit in the front of my Phantek Enthoo Pro, but that's what I get for not reading the product dimensions. It works fine on the top, so whatever. CAM software works fine, which I suppose should be enough to raise this to a 4-star review even though in my heart I find this a 3-star. Have to counter all the other negative-nancies who can't get their software to function. Not that I think they're doing anything wrong, but my girlfriend thinks people who can't get their stuff to work most likely don't know what they're doing so I'll have to take her side on this. Sorry guys, git gud. Her words, not mine. I swear.[Edit 7/23/17]I've since reapplied the thermal paste and moved the radiator from the top of the case, where it attaches properly, to the . . . kind-of-in-the-front of my case. It is way too large to act as my actual front intake, but I've attached it with command trips to the side of my hard drive cages and it has been a miracle worker. My temps at idle dropped 5 degrees to where it always sits as warm as the liquid itself, usually a 32-34c. At load it dropped from 75 to 65c. This has now definitely crushed my stock cooler, and I regret ever writing that about it. Bumped it up a star for performing as advertised.Picture attached for my ghetto mod. The command strips can't be seen from any angle, and I've braced it on the bottom with cotton swabs. A violent jiggle test ensured the command strips held it firm. The Phanteks Enthoo Pro was not designed to put 140mm fans on the hard drive cages (the holes only fit a 120mm), but from this experience I have to conclude that command strips are a viable mounting mechanism.
