Very hot RTX 3080 Gaming Pro from Palit. How to change thermal paste on a video card?

Greetings my friend. In today's video, I will tell you about how I purchased the RTX 3080 Gaming Pro video card from Palit after mining. This card is not in the best condition, it is very dirty, thermal pads and thermal paste are in poor condition, tests showed very high temperatures, after servicing the GPU and Hot spot temperatures are noticeably lower, but the memory temperature (Micron chips) really worries me: 102 degrees. If you have encountered this problem and know how to solve it, I would be grateful for your advice (write in the comments).
