/sigh, fail, fail, and more fail.
The only laptops that'd fail from "extensive gaming" would be the ones that are poorly designed, shoddily constructed machines that only pretends to be designed for gaming. Yes, the form factor has relatively limited thermal profile (which btw still varies greatly depending on the actual engineered design), but then again that's what mobile version of cpu/gpu are designed to work with. You get less performance, but also less heat generated. Any gaming system worth its salt will deliver the rated performance while keeping itself within the thermal envelop. And as long as chips operates within its rated temp, longevity is not an issue.
If what you claim is true, then there must be a mountain pile of complaints about failing sager/clevo, and more recently asus/msi gaming laptops by now... except there isn't. I'd strongly suggest you to actually go out and do some actual research instead of holding on to... whatever it is that led you to this rather disconnected view.
poor design and maintenance kills laptops, games doesn't.
FYI, my overclocked gaming laptop is well into its 3rd year and is doing just fine, and no, it doesn't have an ac running underneath it
