Ok I think I've got my wc setup planned ok, I'm only cooling the cpu and mobo chips to begin with. I don't have a lot to spend at the moment on kit so I'm going for a Swiftech APOGEE GTX and Black ICE GT Stealth 240 Radiator with a 12V X2O Compact 400 pump. I am still not sure what chipset blocks to go for. It's to fit a p5n32-e sli mobo (680i). Also the northbridge and southbridge heatsinks are connected by heatpipes to larger heatsinks towards the top of the board around the cpu socket. Are these larger heatsinks sitting on top of something else? (VRMs?) or are they just bolted to the board for increased surface area for the nb and sb heatsinks? thanks in advance guys.
