[SOLVED] AMD Threadripper unscrew and screw back in order?

As I was watching an installation video AFTER I already installed my Threadripper 3970X, I realized that there is an order to which you are supposed to both unscrew and screw in the mounting bracket. (Maybe) unrelated, I was having problems with the build overall, getting performance drops and stuttering in games but didn't see the FPS counter drop. I put in a new GPU of same model (2080 Ti)) from a different computer and it seemed to fix it until I tested my friend's 2080 Ti, which was two years old, in and then it started having the same problems again. Is there a possibility that the oversight in screw / unscrew order for the TR could cause problems like this? I ended up buying a new case which significantly better airflow and temps (according to Gamers Nexus) that I am going to try out since I think it may be a thermal throttling issue for either CPU or GPU. Thanks.

Do you think it's worth unseating it and redoing it again in the correct order? I saw on a reddit post that there is more of a risk to the motherboard pins than there is to the CPU pins which I suppose is a better alternative.
LGA CPUs have no pins, just pads/lands for the socket pins to land into. The tightening order is mainly about the direction in which LGA socket pins will scrape along the pads: the side with two screws (1&2) basically acts like a hinge to ensure the whole thing comes down evenly when the last screw (3) gets tightened so pins get squeezed straight toward that direction. If you tighten #3 first, then pins will get squeezed sideways away from whichever of the other two screws you tighten first and could end up...

The srew/unscrew order is to make sure the CPU pushes down evenly on the socket pins. The wrong order MAY have bent something in the wrong direction.

Re-seating the CPU and tightening it in the correct order shouldn't hurt.
