One of the main reasons we have water coolers is for the performance and quietness. In this the Swiftech system delivers, at least compared the the stock Intel cooler. With the included fan the H20-120 is fairly quiet, but when we put a Vantec Stealth fan in it basically didn't register on our sound meter. Cooling performance was very good especially when overclocked, with the system being from 5-10°C cooler under load than the Intel cooler.
