As I'm sure most of you know, C/W values are proportional to the die contact area. Since I am considering re-making my die I am once again re-thinking the surface area to use. My first brass die is 84 mm2 (XP T-bred) but given the chance to do it over...
I suggest we "standardize" on 100 mm2 die surface area. This is a nice even number that also matches the Barton core (101 mm2). The Opteron and P4 with integral heatspreaders are too big for a die sim IMHO.
The aspect ratio of the die (width x length) is probably much less critical than the total surface area. The Barton core is 7.42 x 13.61 mm. I'm thinking of using 7.50 x 13.40 mm for my new Cu core => 100.5 mm2 or maybe we should just go with 10 x 10 and not worry about it.
What do you think... ?
