It seems highly unlikely to me that the CPU running hot does it any harm. Intel turbo boosts up to 100C and starts thermal throttling there because that's what they designed the chips for. Maybe other parts will break because of too much heat around the laptop; if it's on a desk made out of PLA or something, you'd want to keep the computer as cold as possible. Maybe the heat melts the adhesive holding the battery in place and it starts rattling around. Maybe the heat ruins the keyboard. I have never heard of any of these happening... but who knows.

The reality is that what seems "pretty warm" to your hand is nothing to a computer. 100C is hot for them. Dip your hand into some freshly boiled water. Is your computer that hot? Then it's fine. (Don't actually do this.)

It is also unclear to me that disabling frequency scaling results in a cooler computer. Someone should collect some data on how the power is actually used; does it use less power to perform a calculation for 2 seconds at 1000MHz or 1 second at 2000MHz?

Finally, my experience with overclocking is that it's AVX that really makes Intel chips heat up, regardless of frequency.

All in all, I think this probably does nothing. Personally I just use an iPad Pro as a laptop and keep my computers in a datacenter. No fans.
