Hey, I'm looking to build a new desktop shortly (thinking I should wait for Vista SP1 or at least until nVidia releases some drivers to get some better gaming results for their G80) and am considering watercooling. I've never used a watercooling system and have been trying to read up about it. The only silent water cooling system I know of is the Zalman Reserator series. Are there any other systems that are totally silent or near silent?? Is it even possible to cool a single 8800GTX and a QX6700?? Would having two watercooling systems be better? Would it be worth it to include the NB/SB, memory, PSU, HD or any other part in the water cooling loop, and if so what would be the "best" (subjective) pathway? Thanks a lot!!
