I wasn't aware of the two different versions of "Max > Temperature".
I have had laptops which throttled on hot days and when there wasn't enough airflow around/underneath them. You'll see dmesg filling up with warnings about max temp reached or some such and any heavy lifting compilation taking forever to finish, since the CPU is throttling and cutting out. If the overheating was extreme due to a race condition, then the laptop would just shutdown. Since you have not observed this kind of rather concerning symptoms, I think you can continue using the schedutil governor which is quite intelligent in juggling and optimising tasks. Check the documentation for your kernel in: /usr/src/linux-6.6.30-gentoo/Documentation/scheduler/schedutil.rst
