17 R5, to throttlestop, or to let throttle.

Hello. I have the i9-8950HK, and as far as I know, they run hot, especially in a laptop. I'm using Throttlestop to undervolt -110.4mV, which is the lowest system stability allows for, keeping my temps around 90c, and no throttle. Repaste/pad seemed to do nothing for temps, btw.

My question is, is it better to do what I'm doing and stop the throttle and the 100c temps, or should I just allow it to throttle because that's what the system it designed to do? Which is better for overall performance/life of the laptop?

Thanks in advance for any responses.
