The Kraken Plus released in 2025 is not compatible with AMD Ryzen Threadripper™ processors or any processors using the associated sockets (TR4, sTRX4, sRWX8, sTR5) such as the AMD EPYC™ server processor family.
While previous Asetek-based Kraken coolers were compatible with TR sockets, this was due to an included Asetek-compatible mounting bracket included with select AMD Ryzen Threadripper™ CPUs. This mounting bracket is not compatible with newer NZXT Turbine based coolers.
