The Zalman CNPS9700 NT CPU Cooler is one incredible product that is sure to please. If you don't want to install a water cooling system because of the potential risks, then this is a great alternative. I was impressed that this cooler could keep a Core 2 Duo E6400 CPU overclocked to 3.2GHz using 1.55 voltage cool. This is something that's even a challenge for some water cooling kits to accomplish. With its large 110mm green LED fan, massive fins, three "figure 8" heat pipes and a smooth base, it will have no problem keeping almost any CPU cool. Being large certainly has it's benefits in the cooling department, but it might pose a problem in some setups. It's simply one of the best coolers money can buy. Speaking of money, this cooler doesn't come cheap.
