Unfortunately, it's worth taking Intel's TDP numbers with a huge grain of salt. AMD isn't much better, but at least they aren't doing what Intel has done with these 10th gen chips.
Under load, the 10700 and 10700K are very similar, thanks to Turbo Boost. One's rated at 65W TDP, and the other 125W TDP. Yet they both wound up drawing the same power according to Anandtech, with peaks over 200W on both. So unless your machine is configured to disable Turbo Boost or apply TDP limits (neither is the default), it's drawing a lot more when it is loaded down than Intel claims in it's ratings. To actually see what's going on, you pretty much need something like Intel's Power Gadget tool to show you what the real power draw is.

But at the end of the day, I was more trying to point out that heat as we sense it is more about energy per volume. Noise from fans is about RPM required to provide the needed CFM to dissipate that energy. I was more pointing out the 5600X, despite being a noticeably less power hungry chip than something like the 10700 when looking at real measurements, is still harder to cool when you shove it in a smaller box with bad airflow.
Thankfully the 5900X is overkill for what I do. The 5600X was a lot cheaper, and easier to grab one when I did. What stuff I do that does need cores I do on macOS.
