That's one good radiator for a pc watercooling I tell ya. But you need to have a push-pull fan setup on that high-density cooling fins. I've been actually looking for a nice core heater rad for my water cooling rad in the first place. But didn't have a luck finding a good one that fits inside my case so I got a pc rad instead. But anyways, with that rad you should be able to cool down cpu, northbridge and two graphics cards with no problem. As long as you have a good pump and fan setup.
