I have a Dell XPS 15 9500. I have been happily using 18.04 but keep getting told I need to update to 20.04. I've upgraded, but now the fan seems to be running high pretty much all the time, even when the computer is doing nothing / asleep.

Is there anything I can do about this?

ps auxc | grep -i therm

I don't have lm-sensors or vitals but I can install them if that will help.
