First question. Could you run liquid nitrogen through an exsisting H20 cooling system? Could the sub. pump handle it? Also Im running a ASUS A7V kt133 TB 900 @ 1030. I want more. I've noticed that changing the mulitplier from 9 to 9.5 does nothing, the same for 10 to 10.5. Why would the multplier not work for the .5 increase in the multipule? Thanks !!!
