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.
