I used to use SMC fan control on my older MacBook Pro to just run the fan at medium at all times. Definitely miss that you can't use it on the new touchbar MacBook pros.
Interestingly, macOS has been the only OS where I have not had this be an issue. 95+% of the time the fans are off, and rouge runaway processes are quite rare (which is not true of say Linux or Windows, in my experience).
Yes, the only time I hear the fans on my MacBook is when I boot into Windows.
