What batteries do you guys use for your PC Fans?
Also, Correct me if I am Wrong.
Red = Positive Black = Negative ?
Have you ever licked a battery?
Yup, Many times...lol....
Ok now step it up and try to lick the charged capacitor in a television
Believe me: no one ever did that twice!

^^if you don't want to die, you can try those camera flash capacitors on your tongue, those will teach you about pain.

^^BBQ anyone? (Sorry that was really sick... I'm going to hell for sure).
That picture looks familiar, didn't that guy survive?

Ok, but on to answering the question:
PC fans draw in the low milliampere range of current at low voltage, it's nowhere near enough to hurt you.
24 AWG wire is pretty good for this sort of thing.
And i'd reccomend a 9V battery over a 6V one.

I have found that my twelve volt pc fan, when connected to a fresh 9v battery, only starts to spin if i "dab" a wire on the battery to kind of jolt the motor.
It only happens if i don't use it for a period of time.
What do you guys think? Shite fan or what?

I have this same problem in one of my combustions bro. I'm not sure if it's starched up or the 9 volt will no longer spin it from a stop. When I flip the switch to turn the fan on it will make a jerking motion but stop.
Would two 9volts turn it?

Does it spin freely when you try ans spin it with you fingers?

Just give the fan the voltage it wants, this will give optimum results.
For the most fans, this is 12V
Its even possible to run them at higher voltages.....

I just thought about using two 9v with two 3 volt l.e.d 's to reduce the voltage. Plus i would have pretty lights on my cannon.

Iv'e run them at 18 volts with no proble, btu those were mid size to large fans. And Novacastrian, you could just use resistors.
