Do you think I could move enough air running a 12v fan on 6v's, and would I mess up the fan? if I cant run it on one I have to make room for too 6v batteries (which are pretty big) . the chamber is 15" long and 4" in diameter.

You can't hurt electric motors by using less voltage then they are designed for they will just run slower (or not at all). Now overvolting electric motors on the other hand can easily damage them.

i hooked a 9v battery up to my 12v fan and it is so slow so i am thinking of getting a 12-24v drill battery to get it goin a little better but i will see how it goes because those batteries arent cheap.

How about 2 9v batteries in series through a $1.59 <a href="http://www.radioshack.com/product/index ... earch">12v regulator</a> from Radio Shack?

Use a 9v battery and 2 AAs, that'll give you plenty of power without the need for extra parts
