Does computer hardware use physical thermometers or is it an extrapolation by software of how much strain is on the hardware?

I forgot how they are called, but you have these kind of components on circuit boards that have fluctuating resistance based on how hot they are. And that's how the computer calculates the temperature of various hardware.
So to answer your question: Both. :P

Like dickquerro said, integrated circuits can measure temperature in a few ways, but temperature sensitive integrated circuits, like the one explained here: http://www.facstaff.bucknell.edu/mastascu/elessonshtml/sensors/templm35.html give a voltage output that is directly related to the temperature of the circuit itself.
These types of circuits are known as Thermistors (https://www.facstaff.bucknell.edu/mastascu/eLessonsHTML/Sensors/TempR.html).

LM35, that's right.... God I even used those things in my school projects a couple of years ago. I just forgot how they were called. I was looking at names like thermal conductions or whatever.

Cheers you fucking nerds! :D
