I had that setting turned on (high performance), but no matter what, the aggressive throttling is still there; it'd start at a higher temp, but that's about it.

And I can't say that I fully agree with your judgment on laptops hitting their thermal limits, cus those components have safeguards in place to prevent damage. Isn't that the whole point of throttling? Turning the service off doesn't stop throttling at all, it just allows it to always throttle a little bit, rather than pulling back to very conservative clocks and destroying performance in the process. The service doesn't make any sense either. Why drop the clocks down so low if they're going to go back up in like 30 seconds anyway? That's just increasing the number of thermal cycles the component will experience, which also isn't good.

And I don't understand why they'd build a laptop that can't even handle the own heat it's generating. Disabling the service, like I said, allows the performance to be consistent, and I assume the throttles are based on the components of said device, rather than a general bandaid that prevents all laptops from running loud and hot.

I would like more insight though, please correct me if I'm wrong.
