Yeah, especially since you see it on many EVGA units and also Cooler Master uses a Switch for that as well.
And in some markets that patent might not even be enforcible because its not innovative enough to be a valid patenten.

But the Semi Fanless Chip might also have a pin to set min voltage and or override the "0V Operation"...
