"With today's graphically intense games comes the need for high-powered video cards. But with the speed demon cards there also comes a lot of heat and for those of us looking to overclock these cards, whether it be to get a few more FPS in their favorite game or to move them a bit higher in their quest for 3dMark supremacy, the issue of heat becomes even more important. So enthusiasts have begun including water cooling for their video cards to go along with highly overclocked water cooled CPU's.
Today we will be looking at two drastically different water blocks with one common goal, to get the best possible temps for your GPU. I have dealt with Danger Den and Swiftech a lot during my days as an enthusiast and both offer top of the line products along with their commitment to customer service.
Lets take a closer look at the contenders."
