I have a few old transformers that output 12volts at 300milliamps.
I was wondering if it was all that important to use resistors to get
the current within the stated specs for a pc case fan I wanted to try
to run on it.
I have a fan that states 0.2amps and another that states 0.45amps.
Would it matter much if I used this transformer for either of these
fans as it is now?
Or would it likely ruin either fan?
