1. It'll cool the vid card and chipset no problem but don't expect any miracle drop in temperature. So I recommend you going with a cheaper custom build, with a heatercore and a silent 120mm fan, and better waterblock for the GPU(I recommend the Dangerden Maze 4 GPU or the Swiftech MCW50, the Maze4 performs a little better but requires a slightly stronger pump), because the Reserator waterblock for video card is really bad.
The GPU unit I planned to use with the Zalman Reserator is a Koolance's VID-AT1-V06. Other than liquid gas coolers, I don't know of any water cooling systems that bring the temp below ambient?? So I guess, I don't understand what you mean by "miracle drop in temperature"?
temp drop from the stockcooling on the x800xt. The reserator isn't the greatest thing in the world, so i recommend something smaller that fits in your case with a silent 120mm fan, and it'll perform much better.
the reserator is actually a reallly good performer
the reviews show the temps after it reasches its highest temps
they just dont state taht it takes like 6 hours to reach its high temps
It'll do well
only problem is that its external
I have it runniong a 3.2e @ 4.0ghz with 38-42 degree idle and like 44-46 load
