Can't you just cap the fan speed? Or does it actually get too hot at a lower fan speed to where it would throttle or crash?

I wanted the full power when doing long compiles and such. Just not the fan jojo acion when neowsing the web or writing.

Also swapping the governor was trivial and reliable. Modifying fan profiles has always been a bit of a struggle for me, with huge differences in hardware support, persistence etc.
