CPU and GPU graphics cards use thermally conductive plastic in the internal part of the notebook computer to conduct heat. The thermally conductive adhesive that has been exposed to high temperatures for a long time is easily aging and eventually lost, causing the CPU or GPU to overheat. The notebook computer will not start after overheating.
The copper heatsink plates will help you solve the heat dissipation problem caused by frequent crashes of notebook computers.
