I guess. It is a small draw anyway, but if it were a toss up, I'd rather not add to the mobo's PS burden (or the graphics cards). In a multi rail system, you'd most likely put the fans on the 5v rail. GPU and Mobo are on the 12V rails.

Again, yes and no. While the overall amperage is small, it's pulling it from the 5V line which normally doesn't have a whole lot of amperage to supply.

Therefore, everything is relatively uncertain.
