LOL no race car batters, i need a fan with those specs for an industrial control panel that's about 6ft wide x 7 ft high x 1ft deep. The fan that's on there now is some puny one with 80cfm and it's just not enough. I have 480v, 120v and 24v already going to the panel, so it'd be easiest just to use what i already have, rather then using a transformer to get 12v. Thanks a lot for the links, that's exactly what I needed 😀
