We'll have to disagree on that point. I can stress a CPU to the point where it is being pushed to it's absolute limits and it will continue to run fine like that indefinitely (or at least for the useful lifespan of that computer).
In fact, with every system I build, I do precisely that: I run the system flat out for a minimum of 3 days straight and I purposely severely limit case cooling to ensure that the system is stable running flat out.
Remember, the boost settings are not meant to run forever. They run for a period of time and then the CPU automatically throttles back. The CPU will run hot, but within design specs. After all, the whole point of these various boost capabilities is to allow you to safely run at higher than base speeds. If you don't want to take advantage of these capabilities, then what is the point in even having them? A modern CPU is specifically designed to run in these modes without the need of any user intervention whatsoever.
Any modern CPU will very closely monitor and regulate these modes to allow operation within safe margins.
Now, if you are performing extreme overclocking and purposely running your CPU out of spec with higher frequencies, altered voltages, and you are purposely defeating the design specs, etc. then we have a different story.
The bottom line is simply this:
If you have proper cooling and are not doing extreme overclocking, there is no software - no game, no high intensity compute app, nothing - that can overstress your CPU. The CPU will self-regulate down as needed.
Let's also use some very basic logic here: If running at 100% processor state was in any way detrimental, why would Microsoft choose to make that the default setting and why would AMD, Intel, Qualcomm, Apple, etc. all use such techniques if they were not 100% safe?
