question for you guys. didn't want to hi jack the other guy's thread. does anyone use a blocking diode on their fan setup? i have heard this is a good idea to protect the relay from reverse current when the fan shuts off. how do you do this to make it work correctly?

i have mine going to a double pole relay that opens up the fan so there is no feedback. and yes a dc fan spining will generate power.
