Yeah, that's some tall RAM (I have a Ripjaws X 1600 kit myself).
Well, like I said, if you install the 212 Evo so that the fan is is parallel to the RAM, you can just raise it up (what
I would do). It's also possible to just switch the fan to the other side of the cooler and make it a "pull" fan, instead of a "push" fan (it's the fan that causes the problem, as you can see, at least in that configuration).
