ptanner, That more or less corresponds to my intuitive ideas of what is best. The numbers help and we can easily see that with bad paste the interface can be a sigificant hindrance. I use a silver paste I made myself with about 95% fine silver powder. It is conductive and I use it on an overclocked 600 mhz duron to 900 mhz. It runs very cool. I varnished the duron where the exposed caps and other electrodes are on the surface and used a copper spreader that is very flat. made up a pound of the paste in a small ointment jar. Biggest problem is it settles with time so whenever i want to use it I need to stir it,
The Asus sensor tells me my CPU is at 95F and the mobo air inside is at 85 F which is good cooling indeed. Temp sensor is on the copper plate directly next to the CPU. The cooler has a high speed fan, but is quiet.

So we can see that it is easy for the use of very thin silver paste along with super flat contact areas with a copper spreader we can drive the Si die down to a fairly low temp. Easily in the area of a 35 degree temp reduction with the Si 28..

AMD is supposed to announce some kind of deal with Isonics tomorrow that might include a financing by AMD to allow Isonics to ramp up. they are reputed to be abke to produce about 20 tons of Si28 this year. When turned into pure Si billets suitable for slicing into wafers that looks like it will make around 50,000 wafers and if each one makes about 200 working 1500 Mhz Durons = ~ 10 million parts. Of course some could be copper Athlons and i am sure some kind of mix will ensue. However in future years they will nned a lot moe than 20 tons. It looks like AMD may have the first foot in this door as there is no mention of Intel anywhere?

My estimates for how many parts can be made from 20 tons of Si 28 may be wrong. Anyone care to guess the number 20 tons could make.??
