My electricity price changes every day. You dont got anything like that? Im having trouble seeing that Eth enlargement pill would increase your power without reporting it. Same with the heat issue you are experiencing, it should not be possible, since there are sensors on the GPU, and they just report what they feel.
My electric cost is a flat rate, year to year. The room ambient temperature shoots up 15 degrees, only when using the enlargement pill and the GPU's are absolutely hotter when running it.
