I found dropping the CPU voltage decreased temps drastically. Have 2 friends (both twins, both have 5800x, one with a X570-E, another with X570-F) Identical systems, apart from that, I got one to decrease their CPU voltages and idle temps dropped 5-10degrees. Seemed to be even more under load. This was all done over Discord and they have little to no overclocking / benchmarking experience. If you look on reddit there's a few reccomendations to go off, my 5800x isn't here yet, but just seems to be the way they run tbh.
