Ok so i've run a stress test with AIDA64engineer, i've reach an average temperature of 74°C and a peek at 81°C.
I'm really worried about my temperature because i had a AMD FX-8300 with the same cooler and it rarely reach 50°C even while gaming. And FX-8300 has the TDP of 95W, same as my current Ryzen 5 3600X.
Not too surprising, Ryzens have quite an aggressive boost that pulls a lot of voltage. Temps that high on that specific cooler is funky though. I'd try repasting (use a pea sized blob, rice is too smol) and make sure you have the cooler mounted with the correct pressure (most of them have springs, so you just tighten the screws till they're snug and the springs keep the right tension).
