Thanks for replies so far, I will go with a copper design and have a few ideas in mind. A couple of questions again though.
Firstly it is fairly clear from a lot of the designs here that fairly thin bases of 1-2mm is common at the point directly above the die. However what about the mass of the block, is there any benefit (either way) of having less or more copper in the block.
Secondly, with the above in mind and also the use of a smaller radiator that the Shuttle design limits, would there be any advantage in any access copper being machined into fine deep fins to give it some air assistance to cooling. Rather like an air cooled cylinder of a motorcycle or model aircraft engine.
Finally is there any free or demo CAD systems that can be downloaded to use for the designing, or I will have to do some basic ideas in Paintshop Pro.
Thanks again
