My system is air cooled.I am not sure I fully understand the issue, but let me make a couple comments.
Is the system water cooled or air cooled?
- The curve controller you show appears to be working as you have it set
it starts at 45C and the source is at 38C, so the controller is not active
but you are seeing the 2.1V minimum set to the fan
- The minimum you are applying to the fan IS a minimum
meaning the fan will not drop below that value
but can run above it
About your first comment: you are right in everything except "controller is not active". Controller at temperature below minimum is setting voltage value corresponding to the minimum temperature point in curve line. In my case, voltage at temperature 38C is corresponding to 45C and voltage must be 17,5% = 2.1V. And it is 2.1V as must be.
point in curve line. In my case, voltage at temperature 38C is corresponding to 45C and voltage must be 17,5% = 2.1V. And it is 2.1V as must be.
About your second comment: you are right.
All work fine when minimum power is zero, and fan is "Power controlled"
At 38C, the voltage is 2.1V (RPM=330), and when I set minimum power to 2.1V, the voltage grows to 3.8V as shown in second picture. After setting "minimum power" to zero, the voltage decreasing to its normal 2.1V.

Now in new firmware I create controller with "preset value" and set power to 50% ( 6V ). The fan speed is 1135 rpm.
When I set minimum power to 33% ( 4V ), the voltage grows from 6V to 8V ( from 1135 to 1417 rpm )
When I set minimum speed to 600 rpm, the rpm grows from 1135 to 1279 rpm ( from 6V to 7V )
