It might look insane compared to what you were used 
    to seeing a decade ago, but it's actually not that crazy.

I'm comparing it to a mid-range system I built last year: an Intel i5-13400F with a $60 closed-loop cooler.

It doesn't go past 45C even during Prime95 runs using all cores. And the 120mm fans aren't exactly howling either.

    First, the temperature sensors got a lot better. Previously 
    you only had one sensor per core/cpu, and it was placed wherever 
    there was space - nowadays it'll have dozens of sensors placed 
    in the most likely hotspots.

That's awesome to know. Thanks for the explanation.
