Question about Noctua NH-L9x65 chromax.black

Should easily be sufficient, according to the official compatibility information (even with "Spatzig" for OC):

I have also decided in favour of this fan for a 7 7800X3D - I can also provide my experience values for this combination if required.

Hello, for more reserve I would recommend a larger air cooler.
