I have most of the parts that pwnt by pat has. the exception is that i only have to cool my dual core opteron and my video. I have a bip2 already , should i buy a pa 160 to use in addition to it? i would set it up very similiar to his but i was only planning on using one d5. so in summary: would a single d5 maintain optimal flow through a bip2/pa160/Storm/Maze4? I am more conerned with noise than overall performance. although i would love to be able to do some moderate overclocking and have excellent temps.
