Interesting: I'm currently sitting in front of a Lenovo T440 which runs
on a 1.9 GHz i5 MPU and has both wifi and bluetooth permanently off and
using wired networking. Its noticable that its fan is never running, not
even on the hottest days this summer, yet its temperature sensors never
show anything above 50C.

I've been writing and debugging C today with the highest internal temp
shown being 37C and no fans have been running.
