Is a simple potentiometer ok for controlling DC muffin fan speed?
I'm using a 12vdc 1.5amp switching power supply to run a couple of .5amp 12vdc muffin fans and would like to be able to adjust speed. Just stick it in between them.. no?
What Ohm range is appropriate for this? I'd just like to drop into radio shack and grab one.
