Negative curve optimizer steps are not improving temperature really. All curve optimizer does in the end is raising clocks on the same voltage.
Here is how it works below in pic
You are lowering the V/F curve from red curve to blue curve. So lowering voltage for any given frequency.
You would think that you are going from point 1 to point 2. Because the voltage is dropping... current (Amperes) is dropping so does power consumption.
Yet because the CPU is set to deliver max performance at any given moment it goes from point 1 to point 3. And this applies to any point on that curve.
So it raises clocks because it can, so current(A) goes up again and power is staying around the same.
Voltage/Frequency curve (V/F)
So it pushes the limits of stability. Doing additional CPU undervolting or adding frequency (+25MHz steps) can throw it easily out of those limits.
