As long as it says under the throttling temps, it will perform normally (95°C). Running at high temps by itself if not necessarily bad for the hardware, it's the heating and cooling over and over that will reduce it's lifespan (more drastic temp changes will wear it out faster). Normally I'd suggest trying to stay under…
