Ryzen CPUs run super hot due to the voltage AMD has allowed them to run on out of the box (which are still safe, but makes CPU very hot).
Downvolt it using Ryzen Master. With this you can also set up a profile in which, if activated, the CPU doesn't change frequency up and down and runs on its highest clock in a stable and static manner. I was able to downvolt to 1,15V for 4200MHz on 6 cores on Ryzen 3600 easily.
