Further testings shows even more improvement than I thought since I "fixed" it. Temps are a 1-2 degrees lower on average and more stable. Almost straight lines in OCCT graph instead of all over the place.
Plus previously tested OCs run at lower voltages now. ex. OCCT small @ 5.1 GHz needed 1.32V before and now is stable at 1.30V.
Overall a win for this learning experience! Relid your chips with some silicone or adhesive and don't use excessive force in the process or when mounting the CPU cooler.
