I use a 12V rechargeable cordless drill battery, but a 9 volt and two AA's in series works fine (just doesn't last as long).
If you can't solder, alligator clips and electrical tape are your best bet. A cheap soldering iron is about $10.
Peace,

Even a lighter and electrical tape / heat shrink tube will do.
Strip the wires, twist some fine solder onto the bare wire, heat with a lighter, then insulate.

Starting voltage for many computer fans is 7v, below that it won't even start
My fan used to run off a 6v battery and pretty fast too. Maybe some fans just suck ass?

Many, not all lol. I have a brushless fan with a max power rating of 5v, starts at 1.5v. hmm this actually reminded me, I could use that 5v blower fan to mix fual, it blows air in 360 degrees instead of only one direction.
