I think the correct terminology is “don’t start running the fans at high(audible) speeds till >80C.

  Apparently they don't start at all until 80C here: https://www.youtube.com/watch?v=wgeh7ZJRhZU https://www.youtube.com/watch?v=wgeh7ZJRhZU

    Mine runs at >6k RPM after 50-something Celsius.

    Mine are running at 2k RPM ~40 C.

  Depends on the model. The MacBook Escape (non-touchbar Pro) doesn't run fans at all at low temperatures. I actually thought it was broken when I first got it, but it's intentional behaviour.

  It really depends on the model. My older MacBook Pros would idle at 2K RPM, while my new MacBook Pro can go all the way down to zero in the winter or with very few things open but generally stay at 1200 RPM during daily usage. All of these are silent, of course.
