I remember just over 5 years ago at CES was the first time I had ever seen a sealed water cooling system. At the time, it seemed a little crazy. How would it fit various PCs? What about maintenance? At that time the only real options were custom setups using parts designed for fish tanks. That company introduced their kit later on (Cool-It’s Domino), it had its share of problems, not to mention trying to convince people you weren’t crazy when you said you want to put water inside of their PC. Years later it feels like everyone has gotten into the market and those designs have improved year after year. Cooler Master for the last few years has been trying there hand at it. Today I have the chance to dig in check out their latest model, the Nepton 240M. They have had a few Nepton models before but this is the first 240mm model.
