Does anyone know much about the Sibak AC-02-625B? I saw a little about it on their website. I saw it in a review where it beat all the other heatsinks ( http://tweaknews.net/reviews/shootout27052002/ linked off bit-tech of course) and it beat a lot of the heatsinks considered to be the best. I was wondering how much it weighed. Does anyone know? It uses one clip, so if it weighs too much it should go on the dangerous heatsinks list.
