Is an 240mm Radiator Enough? Tags: Homebuilt Water Cooling Cases Systems halfblazed August 13, 2012 1:31:32 AM I plan on Water-Cooling my system in the not to distant future. I was wondering if a single, high FPI 240mm X 30mm radiator in a push configuration (on the roof) will be enough to cool 2 GTX680's and an over-clocked 2600k. The cards generally run at about 70C on a full load and the 2600K runs at about 50C. I have some restraints since I'm using a mid tower Corsair 650D case. I have the option of getting an additional 200mm radiator for the front but I want to keep that fan as an unobstructed intake and I really don't want the hot air from the radiator blowing in my case. I am getting fantastic airflow in my case right now and I'd like to keep it that way with the additional water-cooling system. The only change would be adding the radiator on the roof. Is there some type of rule that says you need 120mm radiator per component or something like that? I know that generally the secondary card in SLI doesn't get nearly as hot as the main card.
