One thing to beware of wiht CVD, or Graphite, or Carbon heat sink material is the heat moves very well in one one dimmension. There is very little if any heat spreading ability with either CVD or Graphite since the heat moves fast in only one direction and the other directions seem to act as thermal insulators. Now that Carbon Foam thing could be different, but I know from my email conversations wiht a MFG of CVD diamond plates for XRAY machines was that these used for a Heatsink/WB would be rather pointless and VERY fragile.
