    Hi

    I was just wondering what temperature’s everyone has their mirrors running at?

    prior to today, I was using the raspberry pi official case which came with my kit and it was running at roughly 50°C -60°C, bought a new case with fans attached and it’s now running at roughly 35°C -40°C with the same set up of modules.

    Does anyone know what would be the optimal temperature to have the mirror running on?

      I don’t think there is an optimal running temperature, per se, but in this case I would say that cooler is always better. Like you, my Pi mirror runs below 40°C. Unlike you, I have no case for the Pi. However, I do have a small fan sitting above the Pi.

      There has been considerable discussion on the temperature question. Heat is the enemy but if I remember correctly the Pi is stable up to 80°C, give or take a few degrees.

        I agree and think below 60-70°C you don’t have to worry about a thing.
        From 80°C on there is a throttling function integrated.

        I had the early Raspberry Pi4 running idle at 90°C.
        That was scary.

          Thanks for the info!

          That gives me piece of mind. I was worried about overloading it but I’m quite far from doing anything like that now with the case.

          Out of interest, did it affect the performance at 90°C?

            I didn’t check. I didn’t do anything with it, had only raspbian installed.

            I read only later that you can read out performance data.
            With a firmware upgrade it got much better, now running at around 60-70°C. The Pi4 is quite warm compared to the earlier models

              Over 90 RPI will be slow or halted or rebooted.
              And always be careful of a fire accident, your magic mirror might be assembled with many flammable materials - wood, paper, plastic, and dust.

                81 up is when it starts to throttle but can still clock full speed at 81 for a couple of seconds when I was bench testing my Pi4
