Yes, I did run the Pi without overrides for a while and did not notice the Pi would hang on 100% fan speed after boot. But sadly that is not solution for me...
What is wrong with dtparams?
When I open /boot/overlays/README, there is (around line 271) description according to which I set my own config parameters.
I read through some documentation and found that Pi measures fan speed on boot and if no rpm are read, then pwm fan is disabled.

This could give me chance to force enable fan control even if Pi does not receive any tach feedback in the first boot sequence.
So I tried to implement same solution as I found after further digging here:

Hopefully this will work![:)]( "Smile")
