Today my breadboard came through mail and I created my first circuit!
Took a mini fan from an old laptop cooler base, and I made the connection at the breadboard, taking power from a 9V battery. Ok, I might not be Tesla, but I got it working
Now, playing around I also powered the mini fan using a smaller 1.5V battery. It worked again, this time with much lower speed though.
Now my questions are:

Now my questions are:
- On the fan's label (photo attached) I see an indication of DC5V. I suppose that this is the required voltage that the fan needs in order to run? If so, why did it run with 1.5V as well?
- Should I have user a resistor in the first case (9V)? Or a resistor already exists in the fan's circuit board (located under the label sticker)?
