I hear Itanium is worse, though. :-) AMD actually requires a copper heatsink on all new Thoroughbred chips. I find that amazing considering I have an old Compaq 486SX 33 MHz sitting on my desk with the case off, and the CPU has no heatsink. In fact, it's generally cool to the touch, though it does heat up probably to ~45 C or so when it starts doing work. FYI Transmeta sells Crusoe, a 5W VLIW x86 CPU. It requires a heatsink, but it doesn't get very warm. They're working on Astro which is basically a Crusoe on steroids. (Crusoe = 4 atoms/molecule, Astro = 8 atoms/molecule.) -Matt
