But RPM is ultimately what you care about and is the fan parameter that's universal yet independent of the underlying control. RPM is what determines noise and power consumption.
I forgot to add: I would argue that airflow restrictions play a substantial role for both power consumption and noise, especially when trying to achieve a specific fan speed. For power consumption, I don't even see how rpm would play a substantial role in the first place since power consumption depends on pwm, not on the resulting rpm (or airflow). Guenter
