This looks like an obvious case of a ref that needed to seek clarification on the rule. This is the kind of thing that should only require a little common sense, but it seems like more and more this stuff needs to be spelled out for people to avoid lawyering.

I'd think that if the fan is built in to a motor controller, it's legal as that's part of the controller. As with the practice robot I mentioned above, fans installed that weren't built in should only be a problem if they're unsafe(blades completely exposed).
