[Doink the Clown]

When we saw the first pictures of Inno3D GTX 680 iChill, we knew there was more up Inno3D's sleeve, which another picture with all of Inno3D's products laid out, revealed. It turns out Inno3D has another [longer] GTX 680 graphics card, codenamed "Ice Dragon", which allows users a nice degree of customization of the cooling assembly, called "HerculeZ", by allowing control over the number of fans (1~3), positions of fans (six combinations possible), and even mix-matching the impeller. In doing so, it even makes cleaning the fans and the heatsink very easy. The heatsink consists of a GPU base from which five heat pipes arise, which convey heat to two aluminum fin stacks, with a total of 120 fins.
