I think the biggest problem with Linux is that a lot of self-proclaimed “savvy” computer users need to check their ego… It’s either people that have used Linux since 2008 and want to gate-keep the community because their superiority complex is a poorly built house of cards; or it’s people that have only ever used modern windows and think they are good with a computer that went and tried to install Linux and screwed it up because it didn’t work exactly like windows.
Average computer users aren’t comfortable installing windows and do not feel like they can fix it if something goes wrong…
In my experience with them, MSI laptops tend to run quite hot in general, your OS probably isn’t going to fix it. You can try one of those laptop cooling plates, basically a mesh platform with fans, ensuring cool air is always available to the laptop intakes, but it isn’t exactly a perfect solution.
Really it just needs more cooling capacity - they seem to cut razor close to the amount needed in their designs so when eventually cooling becomes less efficient either through fans getting tired/clogged or thermal paste/pads breaking down, it will not keep up.
