Over time, environmental conditions like dust and vibration can degrade hardware connection links. Periodically inspect your V3 motherboard setup to clean away debris using 99% isopropyl alcohol and a soft brush. Ensure all screw terminals remain securely tightened, as loose physical connections can introduce resistance, generate localized heat, and eventually burn out the board's traces.
