I can't see cork having better heat transfer than aluminum (heck, I've seen it used as 'counter protectors' for hot pans and such). I assumed the layer of cork would limit the effectiveness of the top and bottom plates as heatsinks. But then again, I'm not an engineer either. (shrugs)

Damn the industry and their new 1-year warranties!
