Looks fine as expected. The default setting shows room for up to 95°C, which indicates effective cooling even at about 80°C under high demand.
It’s unlikely the extra noise is worth it. I’m not sure upgrading the fan would help much. 140mm fans have improved a lot lately. My D15 has two fans plus a low-speed ADPater, but it’s running at 6600k—so I guess the CPU stays cool enough anyway. If the room temperature is around 20°C, that should be fine.

I might be overanalyzing, but with a Noctua D15 I thought the temperature would be lower. Probably just normal after all.
It's really hot inside the CPU. I usually see similar temperatures on the 5800X3D, and possibly a bit warmer with the NH-D15.
X3D chips function this way, the heat buildup is manageable. Since they don’t generate much heat, the main issue lies with the X3D cache’s ability to release warmth efficiently.
