Compared to the previous generations of Pis, the Raspberry Pi 4 runs pretty hot. Based on the case you are using and the applications you are running on your Pi, it is not uncommon to see the Pi temperatures reaching 60+ C° (140F°). The Raspberry Pi 4 will automatically thermal throttle if its temperature goes beyond 80C° (176F°), meaning that you will get less performance out of it.
So, it is always better to keep a track of how hot your PI is running.
You can get the current temperature of your Pi by running the following command:
vcgencmd measure_temp
This will print the current temperature as following:
 |
| Raspberry Pi 4 Measure Temp |
The temperature will be reported in Centigrade units (C°).
You can now simply create a script to periodically check your Pi's temp using this command.
