My Ryzen 9 had a default boost limit of 90 °C, which caused a lot of stress to the rest of the cooling system in my PC but it didn't seem to have any problem running like that for a few hours. (Fortunately you can crank it down to something a bit more sensible in the BIOS.) My laptop will spike briefly over 100 °C, but only for a second or two. I can see the 'failure' temperature being a bit higher, but 200 °C seems unreasonably hot.
