OK, thanks for the responses, very helpfull all of you.
I do have a couple more questions though.
If I make the block smaller, ie. remove most of the excess copper and have channels to each area that needs cooling, will this help in the cooling effect? I guess what Im asking is, does more copper (not wetted) equal better cooling, or does the non-wetted copper actually
retain heat? making the cooling water work harder?
:shrug:
