Water-cooled devices are always cool, and it isn’t too often that you see water-cooled RAM modules. That being said, Kingston should have its eye on the overclocking community when it announced its latest HyperX H2O memory modules that are available in dual-channel 4GB and triple-channel 6GB kits, priced at $157 and $235 respectively. Aside from the performance benefits of being able to overclock your RAM modules more due to the water cooling, you have to admit, having water-cooled RAM will definitely make your computer rig look a whole lot cooler.
