In our last ID-Cooling AIO review, we mentioned that there were two main ways to go about cooling a CPU. While that rings true, there is a subsection of AIOs in which the design is to have an open-loop system versus a closed or sealed loop.

For those who are not in the know, what this means in the most basic terms, is that some AIOs are made with removable parts so that one can swap in other liquid cooling elements such as a reservoir, GPU block, or any other block available for the various PC components. Typically, we tend to see this from manufacturers that usually offer all of the custom parts already, but in the same vein, there have been companies that did not offer individual components, offering up coolers like this, like ID-Cooling is now trying for the first time that we can recall. In previous examples of open-loop AIO kits, we have seen various fittings used, some with aluminum radiators, some with copper, and many with added bits like fan hubs, but with all of the previous submissions, the cooler stood out on its own as a product you felt could handle the task with more blocks added into the loop.
