Revolutionary Cooling

The Momentum is the first production amplifier to use copper for its heat sinks. The thermal conductivity of copper is 91-percent greater than that of aluminum, allowing the Momentum to use a much smaller heat sink.

To further enhance cooling capacity, the heat sink uses venturis instead of fins. The mouths of the venturis measure 0.75 in (1.9cm), and they narrow to 0.5 in (1.2 cm) in the middle. As the air in the top of the venturis heats and expands, the shape of the venturis forces it upward and draws more air in from the bottom. The venturi-equipped copper heat sinks make the Momentum’s compact, four-inch-high chassis possible.
