I'm not sure what exactly we're debating here, but I'll assume you're questioning how the same 65nm processor can be hotter than a 90nm.
1. Typically, in a perfect world, linearly scaled down transistors would run faster and cooler. However, when gate oxides shrank down to around num of atoms you can count on your toes, we ran into trouble.. big BIG trouble.
2. Have you heard of static leakage current. When just recently Intel had such huge problems with Prescots, why would you think AMD would be immune? Static power is growing exponentially with each die shrink!
3. The smaller the die size, the greater the power/heat concentration. We're approaching levels in a nuclear reactor. Those bygone days of dinky aluminum heatsink are long over. And perhaps soon we might reach limits of copper's heat conductivity.
4. This is AMD's first attempt at 65nm. Ofcourse it will take some time to fine tune the technology. Especially if new materials and techniques are being used. Intel wisely had already gone through the gruesome trials nearly a year earlier before Core2Duo.
