Don’t make the mistake that I did! I bought the hub and 7 of these fans for an open air Rig. I should had done a little homework before I put it all together and plugging them in. No doubt these fans will move air, but they will also draw more current that the little wire harness can handle. I made smoke in a matter of minutes and toasted the wire harness. I may have missed something but there weren’t any instructions or warnings included. I have no doubt I will be happy as soon as I figure out how to manage the current draw.
