Introduction
When I think of things that are big, I think of things such as the blue whale, an elephant, Andre the Giant and the Zalman CNPS7000A-Cu. One of Zalman's newest coolers in their lineup, the CNPS7000A-Cu comes in at a hefty 773g, dwarfing the Swiftech MCX462 but falling just shy of our current weight champion the recently reviewed 3DCooler ULTRA. What the CNPS7000A-Cu lacks in weight, it makes up in volume. It is easily the largest heatsink that we have worked with yet.
Zalman is a familiar name in the enthusiast community because of their work on quiet cooling solutions when the creed for everyone else seemed to be faster and louder. Zalman got into the market at a good time as enthusiasts became less willing to trade off performance for extremely loud cooling solutions marking a migration to alternative cooling solutions including thermoelectric and water cooling. For the hobbyists who are not comfortable with such exotic solutions there were fewer choices and this the niche that Zalman is looking to fill. The last four years has seen Zalman come from the brink of obscurity to one of the leaders in PC cooling. Recent high profile products include their passive cooling solutions for video cards and their totally fanless heatsink case.
