OK for the cold plate (there was pics in my peltier action thread but not working as yet) I have pulled apart one of these http://www.atomicmpc.com.au/article....=16&CIID=22579
as it uses a large TEC (60x60) and am using the bottom from that to sit on the cpu. At the moment the top of the TEC is not totally covered by my water block and am searching for another large cold plate to help spread the heat load. As I have not had any luck with finding any or being able to get one made for me locally I have gone to another forum member being xie67 (cheers mate) to have a crack at making one for me. With some luck that will spread the heat load and sort out the problem of sizing it all up.
The larger water blocks are not available anymore as they are not being made now. If you did find one it would be wortha fortune as they are very sought after.
