1) CPU cooler mounting bracket suitable for Intel CPU Socket LGA775/LGA1150/LGA1151/LGA1155/LGA1156/LGA1356/LGA1366/LGA1200
2) To install the CPU cooler bracket properly, firstly you need to check the socket type of your CPU. This product support 3 kinds of CPU socket: 1) LGA 775 (Socket T); 2) LGA1150(Socket H3) /LGA1151(Socket H4)/LGA1155(Socket H2)/LGA1156(Socket H)/LGA1200; 3) LGA1356(Socket B2)/LGA1366(Socket B)
3) Put the four hollow transparent pins into the corresponding holes (775/115x/1366) on the bracket. For example of LGA 775, the pins should into 775 position of bracket holes. Then put the bracket on top of the motherboard, and lower the bracket in a way that the pins poke through the holes on the motherboard.
