@MC1Rcat : I have just remembered that there is one Linux developer (System76) I know of who not only makes the
Pop!OS22.04, but also
markets it with a laptop as well. One of the few Linux distros that seems to be marketed towards gamers.
Makes me wonder if System76 is doing something more when it comes to the thermodynamics issues of laptops and Linux. Though it does appear their laptops use a discreet GPU as well, which means better cooling with two fans rather than one dedicated only to the CPU.
That you might also consider experimenting with that distro as well. Another distro I have had much success with, not to mention the GUI is more "Mac-like".
Some of the Linux "gurus" tend to rate it as average, but for me it remains the least problematic Ubuntu-based distro I have found to date. Though I'm acutely aware they are working to deliver a rather different updated version sometime this year.
