Well yeah, but then realize Fermi has a much bigger die (which means heat distribution at x watts will be better than what would happen with a smaller die).
So 300 watts overclocked for 529mm2 Fermi is going to result in lower chip temperatures than 300 watts for Cypress on a 333 m2 die (assuming heat sinks are roughly equivalent). Correct me if I am wrong.
Even if the chip temperatures are lower, you still have to get rid of that 300w heat otherwise it will build up and have runaway temperatures so having a bigger die doesn't really mean much. As long as it is under a threshold temperature (100-120C for video cards these days), the ability of the heatsink and your case to move the heat away from the GPU is what matters (in terms of cooling).
