Although all-in-one water cooling systems are nothing new, their rise in popularity is something very recent. We have watched as multiple companies have launched products designed bring “enthusiast” level cooling to the masses. This type of move is also nothing new as we have watched it happen with RAID, SLI, and many other items that were once only for gamers and other computer enthusiasts Still what many do not know is that most of these companies all buy their parts from the same place; Asetek. This company makes great water cooling products and they resell the pieces to others. Now, while that represents most of the market there are some that still build their own; one of these is Cooler Master. Back at CES 2011 we were allowed to see a prototype water cooling unit and we knew that they were looking to do something very different. Now in last months of 2012 Cooler Master has released their work. Today we will be taking a look at the Seidon 120M all-in-one water cooling unit to see if all of Cooler Master’s hard work has paid off.
