All I am new to the forum. so "Hello"
I have a 12 v DC fan which pulls 8.0 amps.
it has 2 wires. and can easily reverse direction by reversing the wires.
my goal. is to have it pull less amps (sacrifice speed is not an issue)
can I just install a resistor? OR install a potentiometer or similar
It works fine right now its quite noisy at full speed. I tried it @ 6.0 volts
it works nice. after much investigating. Would a speed controller do the same job of allowing me to reduce the voltage draw at the cost of speed?
What would be the least expensive route? and end up pulling less amps?
This is in my vehicle and in the event its running while Im away from my car. I dont want to come back to a dead battery. hence the reduction in amperage usage
Thanks in advance all!
