I don't necessarily want the greatest temps or anything, the reason I went to watercooling is for quietness and the awesome looks of custom water builds.
I will be cooling an i5-2500k and GTX 560 Ti (both overclocked (not looking for 5GHz+ but around 4GHz, GPU I would like to get it to its near max). My plan is to put a RS240 and Phobya 200mm radiator inside a Corsair 650D case.
As for fan configuration, I was thinking a push/pull on the phobya 200mm, using NZXT 200mm rifle bearing fans (800rpm, 23dBA, 102CFM). I doubt a push/pull is needed here since the radiator is only 8fpi, but I still want there to be airflow in my case so I thought push/pull would get more air into the case from the front.
With the RS240 (which would mount at the top of the case (inside)) I was thinking x2 Noctua NF-P12's in pull (pulling air from outside into the case thru rad. I could also mount x2 Noctua NF-P12's on top of the case, and x2 under rad so I would have a push/pull config, but again, seeing as it is 13fpi (not very dense), and seeing as I want a quiet pc, I thought the 2 fans in pull might be enough.
So keeping in mind I don't want great temps, and do want quiet, do you think those 2 radiators will do the job? And please give your opinion about the fans;
If you check the reviews on H2O cooling systems you'll find most do not work well under load unless the fan is running at high speed - thus the quiet mode is lost in many cases - which is my pet peeve with these systems. More fans may help but you will likely need to crank them up which defeats the whole idea.
