PV was right on target with his waterblock recommendation. Brass or Acetal is just a matter of personal preference, I suppose, I would pick brass.
As far as a waterblock that cools the GPU and RAM is concerned, I would strongly advise against purchasing that waterblock because:
- It kills the flow in your watercooling loop severely
- It's three times the price of a waterblock that soley cools the GPU
PV: Believe it or not, I would not recommend all Dandgerden parts. When I purchased my watercooling kit I did not know as much as I do know. Dangerden makes great stuff, don't get me wrong but knowing what I know now, I might have gotten a little more for my money with a couple of non-dangerden parts.
