New build, and if I attach the heatsink, even with one screw twist, I get Asus Error Code 00. I have to Post without heatsink at all, and then lean it in for some sort of heat dispersion.

For unrelated reason, I exchanged the motherboard for same model, but I get the same issue. I want to say it's the processor, but since the replacement didn't fix my other issue, I am not convinced. Any ideas?

Asus Code Z270 and i7-7700k and Cooler Master RR-212X-20PM-R1.

Once started without heatsink, I can put on all the pressure I want. Thats why I dont think it's the processor. I am aware of the thin wafer, and chip itself looks fine.

I was thinking I would make a wild attempt, and put rubber gromets under the heatsink's metal posts. Just to raise it above the board, then coat the metal clips with clear nail polish. Figured it couldn't hurt to try. Maybe there was something causing a short.
