on Pi400 and saw that temperature goes down to 39°C on idle, and up to 53°C with cpuburn running.
This simple command measures temperature and pipes into trend:
120x4 means 120 seconds for 4 minutes according man page.
Code: Select all
$ (while true; do vcgencmd measure_temp | cut -f2 -d\=; sleep 1; done) | trend - 120x4
trend can be installed by "sudo apt-get install trend".

The graph resulted by starting cpuburn-a53, then pressing CTRL-C, restarting and finally pressing CTRL-C again:
I tried 60x1, and I really like that "make oldest data points darkest" in circular display:
