Specification, setup, notes
Even running at 2400RPM, the fan only produces 25dBA. Impressive. Zalman cover themselves from any liability arising from the 773g 7000-Cu.

Notes
The 7000-Cu will be compared to the eardrum-bursting combination of an AX7-478 and 68CFM Delta, and to the quieter, all-copper Cooler Master Fujiyama L71A. Decent load wattage will be provided by a 3.0C overclocked to 3.54GHz. A load voltage of 1.63v will be applied to further push the heatsinks to their respective limits. Ambient temperature hovered between 21.4 - 21.8c. Testing was undertaken in an open-air environment. Arctic Silver 3 was applied between each heatsink and CPU in turn. It was allowed to settle for a few hours before formal measurements were taken.
