I had the same issue with my S17+, these gears are terrible compared to the S17 pro, they are less terrible than T17/T17e but still, the failure rate on my S17+ is 50% easily, and most of the heatsink fell along with the chips unlike the T17s, I also noticed this on the S17, I wish I had the skills, time and tools to fix these chips like you and the other folks, I had some success with the S9s chips but my overall performance was very poor, I had someone else fix them for me after that, and that person is no longer available, so all I can do is watch those gears sit there do nothing.
