Never a non issue with a laptop. Dust will always get in them as with any PC but more delicate with a laptop. CPU works twice as hard with a laptop same as a GPU in such a confined Space.
They don't work any harder, they may get hotter, but that's a given. Also laptop components can work whilst hotter, an intel laptop CPU can go up to 100 degrees whereas a desktop CPU can go to around 80 degrees
