I live in the tropics and the only 1080ti available at a decent price was the Zotac Amp. It did hash very well but did not cool well. I put it at 70% TDP with the fan at 90% to keep it below 70c. I finally was able to buy an Aorus 1080ti with 3 fans and they cooled extremely well, 80% TDP, fan on auto (around 30-50%) with the temp mid to low 60's plus it hashed slightly better. I won't be buying any more Zotacs.
