Curve Optimizer will apply an offset to the processor voltage. Set a negative value across all cores. Start with something small like -5, and use an all core workload like Cinebench to verify stability, then try -10, etc. Repeat until no longer stable then go back to previous value.
If you don't like trial and error, you could alternately go into BIOS and set a lower TDP. You will lose a small amount of performance this way but have a lot less voltage and heat generation.
