Why does that scare you? Your laptop would be designed to handle the thermal load of the CPU running at full tilt. As well, modern CPUs “boost” up to their full power level, so if they start to overheat they can “throttle” back down to prevent any issues. Worst case, they will shutdown before damage occurs.
Otherwise, yeah, running at 100% all day, every day can shorten a CPU’s lifespan. But doing it for a couple hours here and there is gonna be fine. You get similar usage if you’re rendering a 3D scene with blender, for example.
Nice try movie executive!
