Bill, <I think the chip might have more than 25% of the thermal resistance across it.> Pete just showed us with numbers that realistically it is around 25%. <heat sinks have to be very flat as is the die surface> It is just another resistor in your model: <recall the heat flow equation is a series flow analagous to series resistors> <if they make all the other resistances as small as possible then the lions share of gradient lies across the substrate.> This is a _VERY_ big IF. The other resistances are already as small as economically possible. <Do they make any efforts to make the socket a heat sink?> Some do (using alumina ceramic packages), some not (using cheap plastic). <You would need holes in it and insulation with a fine pitch etc, but doable....> Some estimations of cost would be helpful here. I've heard that the crystalline carbon-12 is a very good heat conductor too :) Sorry for goofing around, Bill:) Best regards, - Ali

Another funny joke from 2GHz-in-january Andrew Thomas : His sources are smoking crack... Fan-free Athlon Palomino 'runs at 1.5GHz' By: Andrew Thomas Posted: 04/12/2000 at 12:42 GMT Following our report last week that AMD was experimenting with a new pure form of silicon (later confirmed by AMD Zone), news reaches The Reg of Chimpzilla's progress with the upcoming Palomino. A new natural substance that disspates heat much better than ceramics is being tested and a Palomino prototype is reported to be running in AMD's Fab25 in Austin at 1.5GHz with a simple passive heatsink. Details of temperatures have yet to leak, but the test chip is said to use aluminium, rather than copper interconnects. A Fab 25 insider said Palomino was "looking good". ® theregister.co.uk
