I am installing a 12 volt computer fan on the back of my stereo system to dissipate heat. The fan specs are 1.2 watt and .1 amp. What do I need to look for in a voltage transformer. I have found a 12 volt, 300mA transformer. Will that work? Do I need to match the amperage? Thanks

It will work fine, in fact, you could safely run 3 such fans from this transformer.
However, you did not say if the transformers output was rectified. These computer fans require 12V DC voltage, a transformer all by itself puts out AC voltage. Its easily converted to DC by inserting a bridge rectifier.

If your Stereo runs that hot maybe it is because you turned the volume up too much :D

Thanks

Klaus, THanks for the quick reply. Yes, the transformer is 12 volt DC. It was previously the power source for Koss wireless headphones that no longer work.
