I have hooked up a CPU fan to a few cell phone chargers and it looks like the fan wants to work, but all it does is pulse a little bit and not actually turn. I've tried several different chargers and have gotten the same result with each. And yes, I have hooked positive (red) wires to positive (red) wires, and negative (black) wires to negative (black) wires. There is a third white wire on my fan, but I believe that is just a speed control and doesn't really affect power going to the fan. Any thoughts? Is the fan just no good?
