When using Opencore legacy patcher, my iMac overheats when the GPU is underload, causing the machine to go into sleep mode and requiring me to close the app quickly or it will keep going back to sleep and ultimately powering off.
According to MacFancontrol the GPU is 110 degrees C.
I've just updated to OpenCore 2.20 and Sequina and the issue is worse. From the get go the game I am using (Rocksmith 2014) starts lagging a lot every few seconds and after about 15 minutes goes into sleep. (On Somona it was about the half hour mark before it hit enough heat.).
This is not surprising as it seems to run hotter even when idle running sequoia. I've had this happen playing a simple game such as Polytopia as well.
This does not happen when using the stock OS / Monterey or when running Windows, so it's not a hardware issue.
