Answer 1

Thanks everyone for the replies.
I decided to check the indicators in Hades, it turned out that the percentage is heated by 80% and because of this, the percentage went into throttling.
I didn’t take out the cooler, because I took the percentage for the old processor, namely 4330, although I don’t know why, because before everything was ok. In general, I changed the cooler and everything was fine.

Answer 2

Well, rejoice that the card draws graphics better than the processor logic.
You can run a hairy donut, then the processor will idle, and the vidyuha will plow and warm up.
