240 Rad enough for this build?

I'm dropping in a simple WC loop in my prodigy build.

I'm running i5-3570k @ 4.2Ghz and a AMD HD7950 @ stock settings.

Would a 240mm be enough to keep them cooler than on air?

I might eventually get an additional 120mm but will the 240mm be enough for both?

How thick? there's a world of difference between a H100 size one (27mm thick) and a 65mm thick EK XTX.

Lets for argument sake say 30mm. In push pull.

Let's also say, would there be a huge difference in 47mm?

Anything?

The general consensus is that for each component you add a 120.1 , so theoretically a 240 rad should be enough for your CPU & GPU but don't expect great temps.

It also depends on the thickness, fin count and ultimately the static pressure and air flow of your fans.

My advice would be to add 120.1 for each component and then add in the total another 120.1.

So for your configuration I would aim for a total rad area of 120.3, it could be a triple rad or a 240 + 120.
