I'm not an expert but my impression was that a fusor isn't cold fusion at all. The device itself does not heat up too much perhaps, but it literally accelerates ions to fusion temperatures of >45 million Kelvin.
Likewise a laser runs at "negative" T, but which is hotter than infinity T (pop inversion happens at T<0). There's no contradiction because T is again defined in eq., so we're just abusing terms.
So if we got net energy out of a fusor it would, for all practical purposes, be "cold" fusion. In fact, it doesn't have a T at all ;)
