The problem is that even a simple apt-get update/upgrade or longer install might drive the CPU into 1.7GHz operation and potentially overheat.
Speaking from my experiences with raspberry pi 3 I'd say it would be nice if there was a way to limit max. frequency as soon as the core is above XX°C, because the governor is just too slow, which results in constant switches between high frame rate and lags. It would be better to limit the CPU to e.g. 1.2GHz as soon as it hits max. temp so we'd have a constant frame rate, like this:
boot @ 1.7GHz, idle prompt @ 500 MHz, app stating @ 1.7GHz, thermal throttle @ 80°C -> 500MHz (lag), cool down to 50°C -> 1.2GHz (instead of 1.7GHz).
Also worth noting is that the latest Samsung galaxy S series devices have the same problem as the RPi3: thermal throttle = constant lag.
Best regards,
