My fan spins too fast so it throws the bar, in order to simplify things I'd like to skip adding in a fan speed dial. I'm using a 9 volt fan with a 9 volt power supply, question is, can I use a lower voltage power supply, say 4 or 5 volts and it still work? Will it then spin at half the speed and not throw the bar?
