I recently purchased a Cooler Master Hyper 212 Evo for my MSI X99S SLI Plus LGA 2011-3 motherboard.

While trying to install the heat sink, I encountered a problem with the stand-off screws. The smaller (K) screws, which the instructions indicate are meant for LGA 2011 sockets, are too short. The bracket screws do not reach without tilting the bracket, which then causes the screws on the other side of the bracket to not reach at all.

I then tried the larger (C) stand-off screws, but they are so tall that, when I stand up my computer, the heat sink loses contact with the CPU and sags down.

The bracket screws are in the LGA 2011 position, and the packaging for the heat sink is labeled as being LGA 2011-3 compatible, so I'm pretty sure I have the appropriate equipment.

Does anyone have experience with installing this heat sink in an LGA 2011-3 motherboard, or encountered this problem with another heatsink?

Solution
The screws are not too short. You're suppose to hold the cooler against the CPU while pushing the screw towards the standoff at each corner in a crisscross pattern so that the cooler doesn't tilt away from the CPU.



^^ This. It's supposed to be really, really tight.
