Im building my first computer and Im trying to attach my cooler master hyper 212 evo to my cpu. I am having issues attaching the the x shaped retention plate to the risers. It is in the right place for my for AM3 socket, but it is uneven. I start one screw in and it lifts the others sides to high to screw in. Its like my risers arent tall enough. I might be overlooking something really simple, but I am just frusturated at the the moment. Any help would be greatly appreciated.
