I'm with kayvonjoon. Sure having a warning is nice, but wouldn't it make more sense to build a machine that can handle the temps it produces. Assuming that the picture above wasn't staged (which, it might have been), that scenario looks like a typical setup for a console ventilation-wise.
Oh and does anyone else find humor that instead of RRoDs ppl will now have RDoDs? Atleast M$ could have made their fatal errors have dissimilar acronyms.
