hello, another noob question. I just received my Hyper 212 evo cooler and am going to install it onto my AMD X4 750K processor, however in the instruction manual it says to choose 1 of 3 socket types, LGA 775, LGA 1156/1155, and LGA 2011/1366. I know my CPU is FM2, and the 212 Evo says AMD FM2 support socket, so which one do I pick? The first pin, second pin, or third pin?
