When the “Big Boss Man” said that we were getting another Koolance full coverage video card block in for review and it was for an ATi HD 4870, I jumped at the chance. Koolance has been around from the beginning and they are well known for their high quality products. As a matter of fact, my first ever video card water block was from Koolance many years ago. One of the main reasons I stopped using them back then is that they were primarily small tube low flow systems and I had moved on to massive big tube custom built high flow systems. But here in the past year or so, Koolance has developed products that work well with both types of water cooling loops. So I’m really looking forward to seeing just how well their block will stand up to one of the industries' favorites, the Swiftech MCW60, as well as Sapphire's own high-end air cooler, the Vapor-X.
