Each device has a pretty unique thermal profile(tablets dissipate heat better than small phones, more metal = better profile, etc) so these things tend to get tuned on a per-device basis.
We had one device I was helping bring up where you could run the GPU full-tilt for ~60s. After that the device would reboot and fail to come up until it had cooled enough. Was a fun process characterizing that device and our workloads in 60s bursts. Couple weeks later they had it tuned in where you could run it 24/7 as the thermal limits kicked in pretty aggressively.
