How long will a 9V power a 12V fan?

Just like it says, I've got a 12V radioshack fan, the smallest available, and I was wondering for those with experience, how long will it last on one 9V battery?

I have a lithium rechargable battery and I stuck it to a mini fan and let it run just to see how long it would go, and it lasted about 8 hours.
