    Great product tho mounting was a bit difficult my case could fit it but I didn't have any holes that matched up well. I bought a new case that said it could fit a radiator this size and while it did I still didn't have any holes to match up so had to get creative. I also bought a bigger version of this but it was open box excellent and was missing the Intel bracket and several screws. So probably don't buy open box but new it looks great and significantly cooled my cpu fixing my frame drop problem I had.

    Great aio. Easy to install. Instructions for beginners super clear. Fit perfect in my nzxt case geeat prpduct and boy does it keep the temp down compared to offbrand 120mm or 240mm i had prior. Do 280 or bigger if your case fits them perfect.

    Great AIO - cables and inputs can be annoying.

    Works well straight out of the box. I've used the X53 in the past but upgraded to this for the larger radiator (2x140 mm fans, too) and the RGB to utilize in my new case. You have to make sure you install it correctly or else air bubbles may accumulate and the AIO won't be as quiet as it can be - also long term use may create issues in the AIO. Just make sure the pump head with the NZXT logo is lower than the intake point on the radiator. I installed mine in an NZXT H510 Flow case and had no issues. You can rotate the NZXT logo display on the pump head unlike the previous X52/X53 versions of this AIO pump. My only issue with this product is the amount of cables connected to the pump head. There is a micro usb to mobo usb as well as a special connection that routes to CPU Fan and I believe SATA. Depending on your motherboard layout this can get annoying with cable management, but it is a slightly smaller cable now versus what NZXT used on the X52/X53. Also keep in mind with the RGB model you need to have the NZXT AER RGB 2 system controller for controlling the lighting using NZXT CAM software. The NZXT "i" cases come with this but not any others. You can still connect the fans normally with any mobo, but you need the controller for the RGB lighting. The fans daisy chain together with a nice short extension to let you do this within the confines of the radiator space, but that does take a bit of figuring out if you haven't hooked up RGB 2 fans by NZXT before. Rating 4 stars because of ease of installation/lack of super clear instructions, and the number of cables at the pump head that should be refined to make for cleaner setups.

    Great performance for the value. It works flawlessly. I just wish NZXT would upgrade/update the fan blade design to push more air through the radiator. It fit great onto my NZXT h510 Flow case. It was a bit of an involved installation. One thing if you plan on not adding any more fans, you can use the included cables from the pump to manage the RGB and fans. No need to purchase an extra hub.

    Havw been my main cooler for the longest now, althouch my cpu (i9-10850k) requires a triple fan radiator, this one can hold up pretty well, am limited to this because of my Mid sized PC Case that restricts me of anything larger. Nicely built and high quality

    NZXT doesnt use a static pressure fan on these, instead they use a hybrid between thr AER and statics. That being said My temps dropped from 65° with stock amd cooler to 42° while gaming. They look great, no pump noise, but you do need nzxt cam and a usb hub for them (i have all nzxt fans and case)
