Will your processor or any other hardware be in that loop?

I think you could get away with the 120.2, though if you have the space, I'd go with a 140.2 or a 120.3. If noise is a concern, you'll almost definitely want to go bigger, but with full fan power, the 120.2 should be ok.

the 240 should do. i only have a 120 on mine with 1 fan. keeps it cool.

Although i really want a quite system, i might give the RX240 a try and see how it goes. If it doesnt work fine ill go for a bigger.

FYI, I built my computer with an eye to quiet, and my loop includes the following: i7 CPU @ 5GHz, 580 GTX stock, and 120.7 worth of radiator. Even in the middle of summer, with my room at 80F, I can keep my CPU below 60C smile.gif And absolutely no noise biggrin.gif
