And a 5570 doesn't need a lot of cooling as it has a low profile. There are even passive cooled versions of it. Yet it's about as fast as a 3870 which in turn is anything from 2 (DX9) to 4 (DX10) times more powerful than a 2600 XT.

Put that in a box at most the size of 2 Wiis and with a 4 cms fan, with all the other components. It fries itself.

No it doesn't. As I said, there are even passively cooled 5570's. Your assumptions are just that, assumptions.

Those passively cooled 5570's need good airflow inside a not too small case. When you are working with convective heat transfer, you need somewhere to place the energy these chips dissipate. If you don't have good airflow, your card burns. Yo can find >100C temperatures in reviews, imagine that in a very small form factor as the WiiU
