how many loops?

[stainremover]

kind of new to watercooling, but i have a cuda box that is just too damn noisy for me. specs are in the sig, but as a summary:

4x 9600gso
phenom 2 940.

would like a mild oc on the cpu / gpus (particularly on the gpus), but longevity is more important. case is a cm 690 so i think i have room to mount a 120.2 of some sort at the top. the other radiators i would have to figure out i guess. budget is a bit tight and im new to watercooling, but i was thinking of starting with thermaltake kits (my local radioshack has a few on clearance) and expanding from there as necessary with extra blocks / radiators. i'm not looking for the coolest temps, mostly for silence on a budget.

my main question is how many loops should i be looking at? one loop? two loops? three? the other stuff i'll try to pick up from reading guides and things of that nature. any suggestions / tips much appreciated.

I'm not a fan of thermaltake water kits. You could build your own for about the same price. Depending on how much you are looking to spend, start with a CPU setup first and build from there. If you want a quiet setup, the Swiftek MCP655 is a great pump. You may be able to get away with a single loop with the right radiator and fans.

actually i was more concerned with the video cards since those are the ones with the most load and the loudest fans. the 120 fan on the scythe infinity is pretty quiet.
