Hello everyone, Let me start by saying I love this site. They number of creativity people here is amazing!! I'm hoping i can pick your brains about something... So I'm starting a new build. I have built two water-cooled systems in the past but it’s been a long time, over 4 years ago, nothing this big and only for CPU cooling. So many new company's and new products, I had to get back into it. Currently I have a Corsair 600T SE and I’m looking for ideas on the number and size of radiators i should be looking at. Too many options, and I’m kind of getting confused. I plan for either an OCed 2700k or hold out for Ivy bridge, two 580 GTX or newer in SLI. I would like to be able to water-cool the whole thing. Currently I know that I can mount a radiator 2x120mm in the top and one 1x120mm on the back panel. My question is would this be enough to cool everything? Would I need to add a second 2x120mm? Or should I go a completely different route? I have seen a couple of builds on here and noticed that someone put a 200mm in the front panel. Thanks in advance on any input you all might be able to provide.
