I geeked out on something like this for my TrueNAS server setting fan speed based on drive temperature with a PID controller. e.g.

(That's not mine. I think I wrote a variation in Python.)

Then I realized: my server is in the unfinished part of my basement where I can't hear it anyway. Let's just run the fans at 80% speed all the time since that's sufficient to keep the drives cool.
