When I've picked up an old computer fan and looked for a power source for it, I've gone to the thrift store and picked out old transformers from phones, answering machines, etc. and chosen them based on total watts, ie. amps x volts, according to the watts on the fan. However it occurred to me that the DC fans in my darkroom on my work truck are 12V, 0.8A, and are wired indirectly to the truck battery which obviously puts out way more current than 0.8A.
So really, so long as current is sufficient, voltage is all that matters when pairing a DC fan with a transformer, correct?
