not sure I get what you mean by my curve, It runs at around 40C so I donīt see the point in making it start spinning >41C?
Your H110i GT liquid coolant runs at 40C?

And - here's the deal. Most PWM fans will run at a minimum speed when they have any kind of power signal, even if the PWM signal is at zero. For them to completely stop, the power needs to be stopped. And there's a minimum speed that the fan can go to overcome the initial friction of just getting started or it stalls out.

Think about your car engine. It can be at 0 RPM. It idles around ... say ... 900 RPM. What happens if it goes down to, say, 750 RPM? Would you expect it to be able to do that?
