have you tried "underclocking" your GPUs?
same as cranking up the fan speed, you can
reduce the GPU and Memory clocks (at least
in principle) through nvidia settings. this should
allow you to adjust the performance across all
GPUs consistently. a little bit of underclocking
can go pretty far in terms of saving power.
