Nah, go with the xp90, not copper, just plain old xp90. Its the most famous HSF... You do not need watercooling, you will only get a few degree less ONLY IF u spent a LOT on the best systems custom made. a plain cheap watercooling will not perform as well as a very nice HSF (xp90 + tornado or if u cant handle noise, a panaflow 57 cmf fan)
