Here's some data from CS:GO gaming:
(the game starts around 13:04, and I join an actual game match around 13:07)
As you can see, the temperature stays around 70C, which is pretty cool, and the CPU is constantly being throttled by the TDP setting.
A quite weird thing is happening here, maybe it can be explained by skin temperature? It wasn't hot at all, it was just a bit warm to touch. But you can see the TDP liming going back and forth from 4.5W to 7W. If I can find a way to monitor the skin temperature, I might find out what's actually happening there.
