Recently we have seen a fair few all-in-one liquid coolers here at KitGuru. While they offer good performance, typically better than competing air coolers at least, you simply stick them in your case and forget about them. Alphacool wants to change that mentality with its new Eisbaer range. The Eisbaer AIO is expandable ? meaning there is more to it than simply whacking it in your case and enjoying the reduced temperatures.
