Recommended way to put fan control into a build

I am hoping to add support for a old seagate nas. It has a fan and by default it runs at approximately 11 million rpm. Not really but is loud. It has a fan control chip and I have the kmod it needs. The question is.. what is the recommended way to put into the build?

  1. a script like the one used for mvebu mamba?
  1. I fancier procd set of scripts? Automatic fan control - Linksys WRT1900AC

  2. Don't put this in the build at all and let the user handle?

  3. something else I am not thinking of?

Thanks in advance
