I'd roll the dice on a 3090.
For the 1080ti, repad and repaste everything first because it's the cheapest and easiest thing to try. Could be anything from an overheating power stage causing panic mode 100% fans thermal shutdown, dying electrolytic cap (replaceable by any monkey with a soldering iron), to the core's BGA cracking from repeated thermal cycles.
Anyone remember doing a ghetto reflow by putting the dead cards in the oven + heat gun later?
