![]() So my conclusion is that the enclosure is not causing any measurable harm in this regard. When I take off the top part of the plastic shell the temperature drops to 47-48. With the basic clear plastic no-fan enclosure and heat sinks the ARM AP runs at about 50C (122F), and my Pi3 works fine. I see the OP's question has been answered authoritatively, but here are my 2 cents worth of experience: If you need such extremes, I suggest waiting for Compute Module 3, which will have range -20 to 80C, simply by not providing the problematic chip at all :) After 15 minutes of waiting I rebooted it and it started working normally.Īlso, I think that the networking/USB chip on the board itself is not rated below 0 C. I recently booted Raspi3 at -12C cold and the camera did not work (first time in weeks, but other times the temperatures over night were not so low). Regarding the low boundary, you should check all the components. This can lead huge waste of time when trying to hunt down software bugs ("why is my program suddenly running so slowly?!?"), only to discover that the wires are too thin, or the heat sink is too small, so beware! In any kind of extreme scenario, it is most likely that your processing power will decrease first, and other problems will appear much later, if ever. ![]() In our lab, we started noticing frame drops and significant degradation of video processing capability, only to find out that 1) it got too hot without the heatsink 2) the voltage dropped below 4.6V due to 5V supply wires that were too long. While you (probably, don't take my word for it) cannot destroy the SoC by leaving it uncooled, the performance will be severely impacted. This is of course the core temperature - the temperature outside the chip will have to be much lower to facilitate efficient heat exchange. My experience with Raspberry Pi 3: The SoC will start to throttle down at approximately 80 degrees Celsius, and will, in my experience, never allow itself to be warmer than 85 degrees Celsius.
