The NVentiv Mach 2 Cooling System

For this test, we used a compressor cooling system from nVentiv (formerly known as Prometeia). Last summer, the Mach 2 was the top-performing model on the market, and was well suited to keep high-performance processors considerably below 0°C permanently. For more details on how it works and its technical specifications, see test .
