Re: 12v 300ma transformers to power pc case fans?

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?

I hope you don't intend to try to run a DC fan on AC?

Read the labels on the fans. If they came out of a computer, they are probably DC, not AC. Make sure that your power supplies are the same.
If they are just transformers, they are AC. If they are 'wall-warts', they could be either AC or DC.
