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?

Why not use the Pc's power supply? It's there, convenient, probably
able to handle quite a few more amps of load, and automatically
switche4d at the right times.



because he has these xfmrs laying around waiting to be used!
