    Usually the plastic grill under the fan vibrates...

    All those fans are standard sizes. Check the voltage probably 24v. Measure the bolt pattern and thickness. Then find another generic one.

    It is probably a DC fan and so the extra wire is most likely a ground wire. Use an ohm meter and you can probably figure out what is what pretty quick. The pos and neg will have a resistance as will the pos and ground. ground and neg should likely have no resistance. Green wire is commonly used for ground.
