I have to help someone with a system next weekend and I am needing ideas. I haven't water cooled in almost 5 years. The setup is in a Cooler Master Cosmos case. The client will not change cases and has hot hot temps with his dual GX2 setup and E8400. The E8400 is on a small cooler master water cooling kit. The client wants both video cards water cooled. Should we leave the cooler master water cooling unit in place or replace it all with a custom kit? I had planned on using Danger Den for all my parts. How would you do it? How many radiators, loops, pumps etc? Would you water cooler the northbridge? I believe the board is an asus striker. Thx for any advice.. until then I will keep reading!
