Depends on the fans used, what the heat load is for each component, and what performance level you're after. Fans can make up to a 5X performance difference so without including what fans you plan to use is alot like saying is 1-5 double radiators enough performance.

You can use this RS series radiator calculator to help you understand what happens as you change the fan RPM, the heat loads, and even what happens if you add a second or third radiator.

A 10C water/air delta would be average performance and a 5C would be high performance.


I would say NO, a double radiator by itself would NOT be enough, you need some fans on there...
