Alright I have a 17" fan which is the same size as the stock one. It's a 12V source can I change it and it? Will it create enough cooling? Also what do i hook it up to to start it A/c fans or toggle or sensors that makes it faster I hooked it up to a battery at 10.2 volts and it spun decent, I hope it goes a lot faster, anyhow. I need to know.
