Hello, I think cooling my portable wii may be interesting. I thought of a few idea to do so. The easy one is using the original cooler, maybe bent the heatsink fins and add a fan. I have this laptop cooler too that would have a good enough fit after modifications and may be cooler that using the original heatsink. The best would be to have it passively cooled, I plan to do some tests with a piece of a nas case. Because I plan to cut a gamecube controller in 2 pieces and put a 7 inch screen in the middle, I'll have plenty of space and I could put the aluminium piece as the back of the portable. If you know that would be enaugh however, I'll have to do some testing.
