Hello everyone! I finally found the time to share my results. I delidded my AMD 8700G, and the temperature dropped by 18 degrees Celsius. It might be even more, but it's hard to verify due to the fan curve issues. I also replaced the power supply with a 210-watt one from an LG monitor, which I bought at a flea market for $5. I prefer the white one. I swapped out the connector—it fits, for example, from a video camera. You cut one side and solder it to a suitable connector. I secured it with heat shrink tubing. I'm happy with the results and consider further performance optimization a waste of time.
