On an X79 board, you screw the CPU cooler down onto the cooler mount already on the board. There are 4 screw holes around the socket built into the X79 motherboard. These are what you use.
You don't use a backplate with X79 (with LGA 2011).
The Hyper 212+ should be coming with an LGA 2011 mounting bracket these days, but it looks like it's sold separately:http://www.newegg.com/Product/Product.aspx?Item=N82E16835103432
