Is what OK? 58°C is OK, 84°C is apparently marginal...


"Officially, the Raspberry Pi Foundation recommends that the temperature
of your Raspberry Pi device should be below 85 degrees Celsius for it to
work properly. That’s the maximum limit. But it would start throttling
at 82 degrees Celsius."


My pi zero figures are 1.2V and 35.8°C
