maybe try to figure a way like cathar said to hit that 4th side. and add a 3rd or fourth barb onto it. that way less heat circulation. even though many will vouch for what was said(including me), however you know its still that little bit more that over clockers just arent down with. now going from the size comparison to the avatar pic, enlarge the channels, cut down on the angles of the curves. you have to realize how much 180* bends (that tight) slow down water. if u get really indepth take a lil some thing from the tc-4, and add turbulators...
