It's an i7 9700K on Asus Hero XI.
I also managed to snap one of the standoff screws, probably because I tried to apply more pressure on the left side, so when I tightened the last screw on the right, it snapped. Ordered some new standoffs.
Thanks for the reply.
When I installed it and later removed to apply an aftermarket thermal paste, 1/4 of the CPU (on the left side) wasn't covered in the pre-applied paste, so the contact isn't ideal I guess.
Any ideas how to improve the contact between the plate and the CPU?
