Sorry for my bad english.
I keep running into issues with the graphic setting and performance. I have a RTX 2060S with the latest drivers, game on an ssd, 16 gb ram and a ryzen 5 3600X.
When i put everything at max settings i get around 45-55 fps, when i put everything on high i get smooth 60 fps. No problem here. The issue is that the graphic card fans keep going to 100% (rpm at ~ 3000) for 2-3 seconds, than go back to normal and shortly after back to 100% in an endless loop despite staying at 69-70°C. This also happens when i set everything on medium or low.
Other demanding titles like Cyberpunk 2077 or Red Dead Redemption 2 i have on high-ultra setting with dlss but without raytracing and it stays on 60 fps and the pc stays silent es ever, fans at ~ 1200 rpm)
I tried adjusting the fan curve in msi afterburner, but the card keeps overwriting the settings and keeps howling when playing Valheim.
Other games i had this issue with was Warhammer 3 Immortal Empires, but this problem was solved when i pu everything onm medium graphic settings.

Can someone help me?
Is it maybe one of the other setting below the graphic sliders?
