Hello!
Acer a715-71g 56DR laptop is very warm. I would like to change to a thermal compound and thermal pad. Where and how thick are thermalpads? (0,5mm, 1mm, 1.5mm)
(If you can help with drawing or picture.)

Thank you.

    I've experimented with the IC Graphite Thermal pad with very bad results. I tested both 1 and 2 sheets on a Nitro 5 (both GPU and CPU). Using the factory heatsink and very tight mounting pressure I saw temps anywhere from 80-96C almost instantly on load. The cores would jump from 40-50C to above 90C in a matter of a second. I've never had worse performance.

    My conclusion was/is that the laptop heatsink and CPU/GPU mounting pressure is insufficient and unintended for thermal graphite pads. You may be able to custom modify a solution to work with several layers of graphite on the processor die, but it will be delicate and a one-off. The direct-die setup of the processor makes paste the superior choice in my experience. I am 20-30C cooler on Noctua NT-H1 paste all day long. 

    I've heard liquid metal is possibly the best choice. However, the delicate install process and higher cost have turned me away for a long time.

    Thank you very much for your experience. I also got this result. As I look at the same motherboard. What is the thick thermal pad for IC chips?
