Ok I've installed the backplate to the motherboard already and the 2 brackets on both sides but I can't get the retention bracket to Clip on. I put both sides on the 2 bars on opposite sides but when I try to lock it in place one side falls out so I'm consfused and feel dum. Don't say it's for amd only because how would it lock on to my i5 4690k the thermal compound isnt going to do all the work it's gotta be that bracket to lock it in place because otherwise its going to fall out. I just cant figure it out, I'll go home and take a pic tonight but I need some type of idea on what to do
