Connect both fans to the same terminal should work also. Propably tightened the terminal screw to hard and broke of the soldered leg. Might try to solder the pin again and carefully tighten the terminal screw.

This is a diagram of the printhead pcb, like you can see both fan terminals (sk6 & sk7) are parallel connected, so connecting both fans to the same terminal shouldn’t be a problem.
