I geeked out on something like this for my TrueNAS server setting fan speed based on drive temperature with a PID controller. e.g. https://github.com/dak180/TrueNAS-Scripts/blob/master/FanControl.tool https://github.com/dak180/TrueNAS-Scripts/blob/master/FanCon... (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.
