NZXT has announced that their three popular AiO watercoolers, the Kraken X62, Kraken X52, and Kraken X61 will be compatible with Threadripper, arriving soon to retailers.
NZXT has been working with AMD and created an adapter for SocketTR4 to allow you to use their cooler in your new system. The retention clip will be supplied by AMD, in the package the new CPUs. This is a good thing, considering the unique new way in which you install Threadripper processors. If you haven't seen the video demonstrating the installation process you can see it below.
