First off installation is a bit of a hassle with this due to the extra connections that the little screen requires. For some this may end up being a dealbreaker because of the fact that it may not fit in some smaller form factor builds or even a Mid-tower ATX build with all the RAM slots occupied.
Furthermore there's a bit of a known issue involving certain AMD motherboards and the USB connection to those motherboards. I didn't encounter this particular issue with a Gigabyte X570 Aorus Master but your mileage may vary. In case you do have an issue, contact NZXT support and they'll provide a usb hub that works as a workaround until they can roll out Krakens with the permanent fix built in or whatever.
One more thing to be aware of is that unlike what the manual says there are only 2 viable installation directions if you are planning on the screen facing right side up. It's true that there is a way to rotate the image through the NZXT CAM software but if it isn't installed in one of the aforementioned orientations then unfortunately it wont be able to rotate it to the correct orientation which seems like an odd limitation but it is what it is.
Okay so the performance of this cpu cooler is good, but I was honestly expecting just a bit more cooling efficiency from this latest pump design but it misses the mark by a non-insignificant amount. I previously used a Deepcool Castle EX which is also a 360mm radiator AIO and the difference in not only temperature but also noise is definitely noticeable and is a bit disappointing for a AIO cooler at this price point.
But let's be honest if you're buying this or considering buying this then the reason for it is most likely because of the awesome little screen that this thing has, and I can assure you that one shining feature was more than worth it for me but it may not be for someone else, obviously. I was surprised at how crisp and clear the screen is for how small it is, and while you can upload your own gifs, pictures or whatever there is a bit of a learning process in making sure your chosen gif fits the way you want it to without a loss in quality or even unexpected cropping or sizing issues. There's a growing number of useful guides online to guide you in how to do this so it's generally a non issue.
Now for the CAM software, I'll admit I've never used it prior to with this Kraken Z73 and I didn't really have a very good opinion of it based of off some very negative things I've either heard from friends or read from users online, but with all that baggage built up going into this I'm relieved to say that my fears were unfounded. The current version of the software has a intuitive user interface with plenty of data and options for those looking to tweak things to their exactly preferences. While the one downside I will mention is that it appears to take much longer than competing software when it comes to fully loading on startup. This isn't too bad of an issue more of a nagging annoyance, but it does take some getting used to as when it finally loads your user profile depending on your fan curve and lighting set up it could range from hardly noticeable, to a gale force disco colored hurricane.
I would definitely recommend this for a certain type of pc builder, this is obviously mostly for show and as long as you do go into this with that in mind I find it difficult to believe that you won't be as thrilled as I am having this stunning little screen inside my build firing off different gifs or whatever I decide to have on the screen. It's always the first thing anyone asks me about when they see my computer because of how unique it is and how clear and vivid that little screen actually is.
Overall I'm very happy and would definitely order this again if I were to build another PC today.
