I had those same sticks in my rig awhile back. (see my sig) I had to use the slots that were not directly under the cooler's fan. Otherwise, they were just a tad to tall. But I could have just slid the fan up a tiny bit to clear them as well. In my case it was easier to just use the other slots.
Sniper series is just a tad taller than Ripjaws X, which won't fit under the Hyper 212 EVO - unless you move the fan "up" the heatsink, which you can do. You may lose a touch of cooling efficiency, but I have never heard anyone complain.
