This question already has an answer here:
I am using my RPi 3B purely for feeding data Flightradar24 (with Pi24 installed instead of pure Raspbian). I assume that usage of electronics and overall load of the device is rather low.
My temperature readouts with small fan installed are:
- 39.7 to 40.8 degrees Celsius all the time, as reported by RPi via command line,
- 34.3 to 34.9 degrees Celsius all the time, as measured by hardware thermometer with thermocouple attached to RPi's plastic case.
Since I saw temperature measured around 46 degrees Celsius on most of the screenshot, I assume above (low load of the device). Correct me, if I am wrong.
Given above and the fact that the fan is quite very noisy, can I consider running RPi 3B with Pi24 completely without any cooling methods, i.e. without a fan and without a radiator? Or is it too risky?
