Really? That should be a sign that your OS or hardware is malfunctioning. Intel CPUs (particularly everything post-Haswell) can idle just fine under 30c. Certain chips can even get near-ambient temps if you pull the clock speed down to S0 sleep mode. If your laptop turns on, with nothing open, and hits 45 degrees Celsius, I think there's an issue with the cooling system. That, or you own a G3 Powerbook.
Macs in general have really strange thermal profiles. I don't think a single one of my Linux machines, laptop or desktop, has ever peaked 70c in a sustained workload. The only time I ever consistently hit that temp range is with my Macbook, when it's compiling something or plugged into a 5k monitor.
> Beyond thermal throttling, I don't see what harm it would be to run a CPU hot. They are expected to run hot and automatically throttle to keep heat in the designed range. It's not an emergency mechanism that kicks in to avoid CPU damage.
Well, yes, there is a risk of damage running chips at ~90c. Intel chips have a junction temp of around ~95-105c, once it reaches that range the silicon will cut power to the chip to avoid risking damage and to force the component to begin cooling off. Sustaining higher temps for burst workloads is fairly negligible, but running your machine hot all the time will eventually take a toll on the internal storage and memory (doubly so if you're using an SOC like M1).
