Can a CPU downclock itself?

Yes it is to save power and to reduce noise.

If the CPU goes below it's base clock, then it's thermal throttling. Under normal work loads it shouldn't go below the specified base clock unless the cores are in a sleep state.

If someone did not use reason to reach their conclusion in the first place, you cannot use reason to convince them otherwise.

Only under load. If the system is idling or doing light tasks it will also clock down since the performance is not needed

Under idle, yes. But 85% load shouldn't be under base clock.

As the others have said, thermal throttle. 

 

Good chance with something that age the thermal paste is at end of life. If you are comfortable working on the PC, grab a new tube/pack from the store and replace the current paste. (ensure you clean it properly before putting on the new paste) There is also a chance your cooling AIO or Tower could be at end of life as well. After the paste is replaced, if you are still having throttling, then its the cooling. a few ways to verify this though, is to get a program like Furmark (free) and run the CPU burner test and see what happens with the results. If its throttling excessively during the test then you know its time for some maintenance. 

 

 

Did you turn it off and back on again?

Get HWInfo so you can see what the CPU temperatures are reporting when its throttling.
