theory: f(x) = x

practice: f(x) = -8 + 16/(1+e^-10x)

Maybe it’s just mine but can we agree that a lot of showers do that?

    • True. But I also tested when my GPU fans would turn on and it seems like the cut-off point was 45%, below that and they’d just stop completely. And normal idle temperature is around 40°C, and with the curve on the left it makes sense that even a 5°C increase would rev the fans up from 0% to 45% making it sound like a jet fighter about to take off.
