NZXT Kraken X63 Liquid CPU Cooler Review

Final Thoughts

With a few changes to refresh the Kraken X-series of AIO coolers, NZXT has improved upon their already very popular line of liquid coolers. Aesthetcically, the larger infinity mirror look of the pump block makes the unit as a whole look more substantial, while the improvements found in the 7th-gen Asetek pump help with efficiency and cooling performance. NZXT has used a pretty dense 24 FPI, 280mm radiator in this kit, and paired it up with two of their Aer P 140mm fans, which resulted in this cooler being in the middle of our test results at idle, but matching the performance of a 360mm kit at load. These results are pretty impressive, and if you have room for a 280mm radiator and fans in your case, the Kraken X63 offers good cooling performance with low noise output.

We are big fans of the infinity mirror look here at ThinkComputers, and the larger implementation of that design on the Kraken X63 just solidifies that position. CAM compatibility means you have full control over the lighting and performance of the cooler all from a single pane of software. And while the Aer P fans aren’t RGB-enabled, they can be customized a bit by swapping out the color rings, though this is an added cost.

Installation of the Kraken X63 was very straightforward, and we appreciated having a physical installation manual to reference when needed. We also appreciate the versatility of the mounting brackets for both Intel and AMD systems, as they allow you to install the pump block in an orientation that makes the most sense for your individual components. Pair that up with the rotating pump block mirror, and you can find the perfect setup for your rig. Available at our favorite online retailer for $149.99, the NZXT Kraken X63 offers elegant RGB lighting, good build quality, and impressive performance for the price. The NZXT Kraken X63 earns a 9 out of 10.
