I hadn't read this anywhere else, but luckily did read it before constructing my Skylake build with my new Kotetsu cooler.

I contacted Scythe, and as boost said above, they will ship me the new screws once they get them (they are expecting them soon). In the meantime:boost wrote:Be careful with Scythe coolers and Skylake! Scythe is replacing their mounting hardware fot Socket 1151. The current version can put too much pressure in the CPU and damage it. The Ninja 4 is still a good cooler. If you get it, you should contact Scythe asap and they will send you a new set of screws for Socket 1151 installation. The reason is, the PCB of Skylake CPUs is much thinner than previos generations: 0.78mm compared to 1.12mm.
Until you will receive the screws, you can reduce the contact pressure, when you unscrew both screws (number 4 in the installation instructions) for the mounting bar (number 3 in the installation instructions) one rotation.
I assume that simply the new screws are shorter, and so don't allow us to tighten them as much. Not a huge deal, as long as you are aware of the situation.
