New coolant technology called Silent-Pipe II

Silent-Pipe II is new way of cooling, made by Gigabyte. It is technology using natural laws to flow air without fan. It works that cool air from outside case is being warmed by heatsink, and then goes up inside. Card have also secondary passive heatsink, all bound together by heatpipes. By Gigabyte this solution should cool card 20oC below standard active cooling and even 45oC below passive fanless cooling. It seems good, but i dont know, if this wouldnt disturb normal airflow in case.
