I have gtx 970 and an i5 4690k, I want to overclock them a bit so will a 240mm rad and a 120mm rad be enough for this? and if I add another overclocked gtx 970 will I need another 120mm rad?
 
Solution
The general rule of thumb is 120mm of radiator per device you are cooling. So for a CPU and a single CPU 240mm of radiator would be enough. For two GPUs and a CPU 360mm of radiator is recommended.
and its easier to just use bigger or more rads than you may need to begin with--if you want to add another 120 rad later it means draining the loop etc

my 240 + 360 is probably overkill--though i am heavily overclocking

but it does mean i can turn my pumps and fans down to the point i can barely hear them but still get low temps
