Cooler of good quality, careful to follow the assembly instructions according to your socket. Application of thermal paste Cooler Master cross. The highlight of this sink is that it screwed with the support to the motherboard and allows a pressure ensured between proco and cooler. My ram is a little high so the fan is a bit beyond the cooler (not a problem if you have too much RAM). The funny thing is that the bios alerts you that the CPU fan RPM is too low. Cooler very quiet and perfectly cooled proco.
