I read up a little on PWM. I probably have more questions now than answers, but it seems what you're saying is although it shows lower output than the input current, this is false information? I don't have an oscilloscope but seat of the pants airflow with/without the DC controller seemed lower with. I'll have to buy something that actually measures airflow to know for sure.
