For sure the ones on the victors can be wired to inputs of the victors, but no other fans can do this. This is a great question for the GDC, my past experience tells me that you would be fine, but it would not be good to get to a competition and have them make you change it. Everywhere that motors are mentioned, they do not mention these, so that would say that they do not have to be connected to a spike to speed controller.
