How fast will it take a 12 volt fan to discharge a 9v battery?

If the 9v is truly at 9v, and the 12v can is connected to it, how long will it take the fan to empty the battery of it's charge? It's a nimh if it matters. Thanks.
 
Well, i see that the fan is 0.10 amp, and these 9v batteries (Plainview, friggen 10 bucks a pop, nimh) are 170 mah @ 9.6 volts
 
I'm pretty sure that the fan will just turn slower at 9v than it would at 12v....

I think that the running time will just be based off mah and the ma rating of the fan.
