Played around with reinstalling the system, drivers. - didn't help! Reducing the frequency of the GPU by 150-200 megahertz helped. Apparently, the manufacturer overclocked it to such a limit that it cannot withstand. Conclusion: very poor cooling (probably no thermal paste) - the edges of the GPU are 70°C, the center is up to 100°C, and this is already with the fans turned off by 100℅; You need to reduce the frequency of the GPU. While the flight is normal for a couple of days, I'll play some more, write back.
