I'm running Ubuntu 23.10 and for some reason, I'm seeing this message because the operating temperatures are too high:

Performance mode temporarily disabled due to high operating temperature.

performance mode being disabled

This is kind of odd to me because it wasn't there before and I can assure you that my temperatures are not too high. See below the output of some relevant commands:

This seems like a false positive to me and I'm not sure exactly how to fix it. Maybe some config file somewhere got borked by a system update. I'm also noticing that even though my screen will blank, it doesn't actually turn off either and I read this is an artifact of Performance Mode so I thought they might be related issues.

How can I fix this issue?

  • I too saw this message on one of my PCs recently. On Ubuntu 22.04.3 LTS. I monitor temperature via Conky desktop displays and no temperatures were high, The Performance radio button was still selected and I can still select between that and the other 2 options. In my case when I ran cpufreq-info I could see my PC was still running at full speed and changing to the other power modes I could see were changing the cpu frequency down as I would expect. So in my case I just put it down to false message and ignored it. But try the command to see what your CPU is doing. – codlord Dec 31 '23 at 16:01
  • It doesn't solve your problem but, you can override the CPU frequency. Here's a GUI utility I wrote: https://askubuntu.com/questions/1141605/gui-or-simple-bash-script-to-throttle-the-cpu/1142671#1142671 – WinEunuuchs2Unix Dec 31 '23 at 16:09
