the rig is finaly done. went with danger den water blocks 1/2 inch tubing blackice radiator with 4 120mm fans push and pull. we had a problem with the chipset on the asus main board. the clasps to hold the water block on to the chip broke off and it fried the video card. we decided to replace the motherboard and video card. Asus p4c800e and raedon 9800 pro. upgraded to ocz ram. we were able to overclock to 4ghz at temps of no more than 80F'. If you are planning a danger den water cooling project be really carefull of the chipset waterblock clasps. if they break your f++ked. i shortened the springs to relieve some of the pressure of the board. i wasnt going to risk the same result again. so far the chipset is mounted well and the rig is running cool and quiet. if you look closeley at these old pics you can see what im talking about. we replaced the board so the images are of the older board.
