It is unbelievable how many people are water cooling these days. The other day, I noticed a father buying his 12 year old son a Corsair Hydrocool External Water Cooling system at Fry's Electronics. You know water cooling is becoming mainstream when a 12 year old kid can buy a kit at Fry's Electronics. In fact, many of our Case Modding Contest submissions have impressive water cooling systems inside (or outside) of their boxes, which proves how much of a modder's and cooler's dream water cooling can be. Today, we have the privilege of testing out two of the latest water blocks by two distinguished companies: Asetek and Swiftech.
