System Temperature

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
