Good news, I bet it had you worried for a while.
My best guess is maybe the lead you first tried was from a 12v rail that was maxed out already on Watts. Using the other lead could be from another rail that had enough watts to run it at full speed. My PSU has 2 rails, some are single railed PSU's.
The sticker on the PSU or instructions show the rails and what leads are connected to which ones so you can help better spread the watts evenly between all your PC parts.
