To be available with AMD Ryzen 7 1800X and Ryzen 7 1700X SKUs, the Wraith Max boxed cooler has a TDP of 140W and measures 105x108x85mm, which should be enough to cope with AMD's flagship SKUs.
The smaller Wraith Spire cooler will be available for the AMD Ryzen 1700 and possibly other SKUs. Measuring 109x103x54mm, the Wraith Spire cooler is somewhat lighter, circular and has a TDP of 95W.
While both Wraith Max and Wraith Spire should keep Ryzen CPUs well cooled, they won't do much with AMD's XFR (eXtended Frequency Range) technology, that should provide a further CPU Boost that scales with cooling.
Some AMD Ryzen SKUs have already been spotted listed with AiO liquid cooling systems, especially the Corsair Hydro Series H100i v2, which should do much better with AMD XFR.
AMD's Ryzen CPUs should become available for pre-order as of today with a full-scale launch expected on March 2nd.
