The fan control seems to stop well short of the fan speed when the control is disengaged and I have noticed that by disengaging the fan control temporarily while doing these things that cause all cores to go to 100%, it lowers the temperatures significantly (for the most part, they stay below 80C). I couldn't care less about the noise.
My question is this: what is the risk of harming the fan motor if the speed control is disengaged temporarily (usually less than 1/2 hour)?
Also, what is the best way to control the fan and what usable speed range should I be able to get under control (right now, disengaged is usually a little less than 5000 rpm, highest under control is around 3800, which puzzles me a bit).

Here are some fan 'live expectancy' numbers:

in theory, mint / ubuntu / debian are now supposed to prefer pstate over acpi, but in my experience it doesn't happen - so, explicitly pass 'intel_pstate=enable' to grub.
the default / automagic config for thermald has been fine by me, but if you don't want the fan to come on, you may need to mess with the settings.
