I believe that the issue is occurring due to the service that is being used to create it.
I am still facing overheating issues even after changed to a 2GB RAM Raspberry PI. This time, I did not even create any streaming services or bash script, only turned on BlueOS. The temperature was around 43 degrees Celsius at the time of starting up, but it kept increasing with time. Could it be possible that the enclosure is causing this issue?
