But if you want an AIO so you have more room to tinker in your rig or because you think they look better, NZXT Kraken X3 and Z3 are still the best. And sure, the Z63 is $100 more than an X63.

NZXT says that Z-3 Series is compatible with both Intel LGA 1151 and AMD AM4 sockets. The Kraken Z63 (280mm) is priced at $249.99, while the Kraken Z73 (360mm) is $30 more expensive at $279.99.

The NZXT Kraken X3 and Z3 coolers are refreshed with even more features including a small LCD screen on the Z-series AIOs.
