I have a TR PA 120 SE on my 3900X and it's doing a bang up job at cooling it, does just about as well (maybe a little worse off compared to the TT Water 3.0 360 ARGB AIO I had before it). It's in a different case though, the 3900X (+ GB X570S Aorus Elite AX) is now in a SOLDAM XR-1 and the Tt Water 360 AIO is cooling my 5900X (+ GB X570 Aorus Xtreme) in a CM H500M case. So, my recommendation is a TR PA 120 or its successor, but IF OP already has a PA120, I don't see a need for any sort of change....
