How do I wire a 12V DC fan to 120V AC source?
In general a consumer device will only draw as much current as it needs, as long as the supply voltage is correct. 

In this case you need to buy a DC plugpack (transformer, rectifier and regulator all in one package - much like your mobile phone charger) that will provide 12V and can provide at least 0.06A. Most plug packs will manage this. 

So you could connect your fan to a 12V plugpack which is 1200Watt and could deliver 100A, but your fan would only pull 0.06A, so this would be a waste. 

You can power multiple fans off the same power supply, just make sure that you can supply the sum of all the current draws when selecting the plugpack. Wire them in parallel. 

In summary, you do not need to match exactly. Just match the voltage exactly and make sure it is powerfull enough to supply the sum of all the currents you need.
