My old case fan says on its back 12 volt dc .18 Amp 2.16 watts and is a three pin connector that connects to the mother board. It no longer works. I want to replace it and have a few questions.

I have an old fan from another dead machine that is the same footprint and connector that says its dc12v .19 amp. Can I use it to replace the broken one, or do I have to match the amps exactly?

Also the one from the dead machine doesn't say anything about watts.

Where would I find out exactly what amp watts etc this motherboard has available on the three pin connector? Or does that even make sense.... Is this all standard and I can plug in any three pin replacement fan?

Thanks for your help.
