How can I throttle the CPU Power in Ubuntu to prevent over heating?

Hi @StableGenius , Thanks for this tip. You got me thinking as I did upgrade my Lenovo M93p Tiny (Tiny Desktop) from 8GB to 12GB DDR3 RAM and swapped the traditional HDD 7200 rpm (Seagate) with a Samsung EVO SSD. Hence I may need to upgrade my AC Adapter.

But before I do that, is anyone aware of some software for Ubuntu that measures the Power usage (Watts) similar to this Windows app (see below - red boxed areas)

If I can somehow measure the Power used (Watts) I can then determine if my AC Adapter needs upgrading. Thanks in advance.
