I don't agree that it is insane. It is less efficient than ideal, but 10gbit over copper is not necessarily dangerously hot or difficult to power.

I have a MikroTik CRS304-4XG-IN on my office desk with three out of four ports at 10gbit and it is perhaps 20 degrees above ambient on the outside. Warm but not hot. Passively cooled design.

A normal Windows laptop runs hotter than that when idle.

I have several 48 port 10G copper switches in my computer room with 40G uplinks. Dell OS9 jobbies. They are a bit noisy, but they don't actually run that hot. I also have some HPE 1G 48 porters and they run roughly the same temperature.

I used to daily drive Gentoo on my laptop. Lovely in the winter!

Yes the noise is my main complaint for my 10G switch. I didnt expect that high frequency part.
