Hello I have a Xeon 1U copper heatsink that I am planning to put onto a my 9800 Pro? I am going to cut the heatsink to match the same size as the stock cooler and drill screw holes and bolt the card and support the extra weight of the video card if needed with wire to the top of the case. Heatsink next to the stock cooler: Heatsink size: Heatsink height: Base Width: I wonder if the thickness of the copper block will be a problem or not (heat building up in the thick base)? I have 3x 120mm case fans blowing air around the card (+ a fan will be placed on the 1U copper block) so the heatsink will get heaps of fresh airflow. Close up of the Fins: Also the fins are not soldered to the block, you can see the find dont make 100% contact with the cutout grooves in the block. Given that copper if 30-40% better heat conducter than Aluminium I dont think this will eb a problem (the 1U heatsink was designed for a Xeon 2.8Ghz CPU). Ideas, Comments, Suggestions?
