If a cooler uses the stock amd mountings - ie the spring loaded bracket - it will fit.
If it uses a custom backplate & custom mounting system it won't fit.
Cooler master & corsair are supplying am4 mounting kits now with new stock , most CPU cooler makers are offering free am4 brackets for older coolers with proof of purchase of the cooler, ryzen CPU & a compatible motherboard.
My Silentiumpc Fortis 3 Malik backplate has been despatched to me (I never expected this from a small firm like them in all honesty for a cooler which hardly sold in great numbers)
