Here's my alphacool & radiical watercooling setup. Nothing ground breaking, just a overclocked AMD64 3200+ & Nvidia 6800GT. It runs my multimedia workstation and assembling was quite a pain (all pci expansion slots are taken up, 3 by the 9" creamware scope dsp sound cards). here's the specs: A64 3200+ @ 2563mhz nvidia 6800GT @ 420/1100mhz msi k8n neo platinum corsair 3200XL 1gig 1x 160gig Seagate IDE 3x 320gig Seagate SATA alphacool complete kit - nexxus xp light cpu waterblock & nv gpu waterblock, 120mm radiator & radiical resrad (with 120mm fan in top of P180 as intake for main radiator), standard kit pump/res (600l/hr). 80mm Slot blower @ 7v, and 92mm zalman fan for the HDDs (lowest fan setting) Overall, a pretty good and quiet cooling solution. Not sure about temps, reservoirs are warm to touch, gpu reading is around 50c on load, not sure about cpu.
