    fan speed is controlled by dimmer ,..does it save power when it is rotating at lower speed or it consume same power as running in full speed??

    i think it depends on the circuit, if you are using a resistive potentiometer for varying the voltage to the fan then the consumption may be the same at high and at low speeds.
