Having recently built a picade with a Pi4 and ran it in a cool room for around 2 hours, the device kept crashing when playing various emulators. After the final crash, it didn't start up again. Opening up the back was like opening the door to an oven and the Pi4 was just steaming. Nothing was obviously melted, but it didn't work again :(

This seems conflicting with what I read about its behavior. It should heavily throttle (underclock) itself, but shouldn't destroy itself. Maybe you got a defective unit or the hot thermal environments caused issues elsewhere (again maybe due to some defect).

  Oh, I'm sending it back to be looked at. The hat that comes with the picade doesn't have space for a heatsink or fan under it (as the instructions are put together to assemble it) so I'm also suspecting that its early doors for the Pi4 and picade still.

  I had a power supply with similar problems which actually started on fire - I had been restarting it repeatedly after it kept (supposably) hitting thermal or some other shutdown condition. Lesson: just because there are protections for going past limits doesn't mean that everything is fine when you are constantly hitting them. (applicable to our current government problems sadly)

  There's only so much throttling it can do. If there really was zero ventilation and ambient temps were hot, components can start melting.

  Throttle but.... will it shutdown intentionally due to temperature?

So. We can't consider the Pi to be passively cooled for normal usage anymore ?

  Depends on the job. If a Pi 3 sized load then passive is fine. If you max out the hardware it will overheat and throttle though, unlike the Pi 3.

We (Pimoroni) have a solution coming for this! The Pi4 has changed the landscape a bit with respect to cooling so everyone has had to adjust. :-) If you reach out to me directly (e-mail in profile) I'll make sure we send you an early sample of our combined Picade X HAT with fan to test out!
