That should have been fixed with the upgrade for the i9s. In your case, make sure the OS is up to date. Run intel power gadget next to whatever you are doing. That will tell you what's going on. It should throttle between 90-100 & settle around 85. If its a temp issue, run a program that controls the fan & keep the fan running high. I have to do that when I'm deployed to keep my MacBook alive in 130F temps. I left for work & left the thing running when a power outage occurred. Temps inside got around 160 at least. The MacBook was quite dead when I got back. I got a new video card under warranty, but the entire MacBook is going...Bad wifi, bad camera, bad video card. It's a pain. That's why I'm looking at the temps so much.
