You should see (and possibly subscribe to) this bug report:
There have been numerous posts in Ask Ubuntu about CPU throttling recently:
- Core/Package temperature above threshold, cpu clock throttled - Lenovo E590
- Set CPU temperature throttle threshold on Ubuntu/Thinkpad
- XPS 9370 thermal throttling ubuntu 18.04
All these posts say the same thing which happens to me periodically:
~$ journalctl | grep 'cpu clock throttled'
Jun 22 10:55:52 alien kernel: CPU4: Core temperature above threshold, cpu clock throttled (total events = 1)
Jun 22 10:55:52 alien kernel: CPU0: Core temperature above threshold, cpu clock throttled (total events = 1)
Jun 22 10:55:52 alien kernel: CPU6: Package temperature above threshold, cpu clock throttled (total events = 1)
Jun 22 10:55:52 alien kernel: CPU2: Package temperature above threshold, cpu clock throttled (total events = 1)
Jun 22 10:55:52 alien kernel: CPU3: Package temperature above threshold, cpu clock throttled (total events = 1)
Jun 22 10:55:52 alien kernel: CPU7: Package temperature above threshold, cpu clock throttled (total events = 1)
Jun 22 10:55:52 alien kernel: CPU5: Package temperature above threshold, cpu clock throttled (total events = 1)
Jun 22 10:55:52 alien kernel: CPU1: Package temperature above threshold, cpu clock throttled (total events = 1)
Jun 22 10:55:52 alien kernel: CPU0: Package temperature above threshold, cpu clock throttled (total events = 1)
Jun 22 10:55:52 alien kernel: CPU4: Package temperature above threshold, cpu clock throttled (total events = 1)
In my case it happens so rarely and with no adverse side-effects I’ve chosen to ignore the errors.

And just so you know it’s not just Ubuntu, from Redhat:
