The kit filled his role perfectly, and installation is as simple as with the original fasteners as long as we have not two left hands.
I therefore recommend this quality kit to anyone who, like me, want to adapt a Noctua cooler socket 775 on a 1366, this kit is a good initiative from Noctua that allows reuse its cooler on new platforms rather than of having to purchase extra every socket change.
Note that this kit is also compatible with socket 1156.
