Be sure to post back with your experience!Just ordered an Optimus Foundation for my 3700X. Surprisingly, there aren't any professional reviews of the AMD blocks, but from what I'm reading online from user experience is that they seem to make more of an impact than the Intel blocks. The plate and micro-fin array is so large on these blocks that they apparently cover the entirety of the asymmetric Ryzen 3000 chiplets which results in rather significant cooling performance gains (some reported 2-4°C decrease in load temps over other top performers such as the Heatkiller IV Pro and Magnitude blocks).
