Not obviously. Copper traces *do* conduct a good amount of heat, and since the GPU has a zillion of traces going to memory (128-bit or more bus) it's a good connection.
There's an issue of Electronic Cooling about secondary heat losses in IC packages, i may get my hands on it (not now though i'm overflowed with work)
BB2K: usually radiation accounts for between 5% and 20% of the total heat transfer, of course depending on the conditions (reflectivity / emmitivity of surfaces mainly). But otherwise the same goes for radiation: heat goes from hot spots to cold spots.
