Everything is qualified at worst case anyway; all the TDP calcs and the fan settings are completed on the wors case for the product range.
Also, values above 100% are a bug atm, so I wouldn't trust the current GPU-Z results. I'm sure the next release or two will fix it.
Roadhog, what are the voltages for each of the cards you listed?
