Adata Shows Off “Liquid Cooled” RAM at CES, Project Jellyfish

We’re getting into the realm of very intricate ideas in cooling components and that’s saying a lot. Your widely accepted air coolers almost always use heatpipes, which are actually engineered with a substance that phase changes inside, helping move the heat through to the fins. As good as that gets, crazy people found out that using water in a loop with a radiator was even more effective, deciding the risk of frying a system was worth the benefit. Now, Adata is taking things to a new level that, while already existing in other capacities, is bound to be a first for RAM cooling.

First, let’s talk about the concept of these modules being liquid cooled. While generally speaking, this is correct, it’s technically somewhat inaccurate. Liquid cooling generally correlates to transferring heat out of the component by means of, say water, as the vehicle to carry it away. It ends up being a simple transfer of heat from the source to the air. The liquid that’s in these modules is called Fluorinert, which is using a process of cooling called “phase change.” This particular chemical, developed by 3M, can boil at temperatures as low as 34c depending on the variant. As liquid boils, it actually consumes a large portion of the heat being generated, as opposed to transferring it to a less heat saturated area. Thus you have the concept Adata is introducing, but while this looks pretty new for RAM, it’s been implemented in the server environment for some time.

In the end, this is still a really neat idea that Adata has introduced. Whether it should be the future of high end RAM or more of a novelty idea, I’m not sure though. Simply put, RAM overclocking typically gives nominal performance gains and metal heat spreaders go a long way to maintaining temperatures. Where this idea would really get exciting is if it could improve on even custom liquid cooling with CPUs and GPUs. Check out the link below from AnandTech for more information, including some caveats with the design at the time being.
