The one downside I saw with this cooler is much the same thing you find with every other water cooled system on the market, be it a multiple loop custom setup or a pre-built kit. The chipset is cooled by airflow from the heat sink when using an air cooled solution. With a liquid cooled setup you don't have the luxury of airflow over the chipset, so it in turn heats up. With a custom loop you can install a water block on the chipset to solve this problem.
