The other laptops overheat soon after purchasing, often with just the bare OS running. There is a 3 yo laptop that my parents still use, but it has to always be plugged in, and the fans will spin loudly even in suspension.

My >10 yo macbooks also have bad batteries. One of them won't last one minute, and will also overheat with minor workloads. They were not immune to overheating when new, but unreasonable overhearing (for the time) definitely didn't become an issue at within 3 years of purchase.

And that's with Intel macbooks. My M1 from Dec 2020 works like new (I'm sure the battery life has shortened, but not in a way that I notice). It overheated a couple times running LLMs—that's it. That's how I know the fans work.

Put KDE and see the overheating disappear.
