Hi, this is a great product but has some issues with staying tightened on the board. I have gone through 2 P6T motherboards, because of the LG1366 nuts on the brackets vibrating loose and causing damage to the CPU socket pins. in essence bending pins at some pressure points, caused by the loosening of the nuts from vibrating loose. The manual for the installation does not have anything to mount on the back of the board to prevent the low frequency vibration loosening the nuts. I'm not asking for a replacement but want to notify you of this problem I have encountered 2 times now.
