Alright the fans in my computer are crazy loud, and all the fan controllers you can buy will only take the voltage down to about 7v which with my fans I dont think will help because I want it to become not audible at night but still move a little to keep some air circulating. I was thinking using a resistor for this or something that will make the voltage drop to 3-4volts to the fans when I flip a switch. Your comments?
