Now Supports AMD Socket AM4 Processors w/ New Mounting Kit

With the release of their new AMD Ryzen CPUs, AMD also released a new socket; the AM4. This new socket requires a change to the mounting system for NZXT's award-winning Kraken Series of AIO CPU coolers. We began including this new bracket in all Kraken coolers months ago. All new Kraken Liquid CPU coolers include the new AM4 bracket as well. This CPU Cooler now supports 15 different AMD & Intel Sockets.
