Hehe it is so funny like nvidia is kinder garden. If i could talk to nvidias people to face ehhh ehh. What happened? Where is gamers that wanted cards? These gpu manufaturerers will never find good customer like a miner 
To be honest I think 80% of the cards are bought by gamers/designers, also there is much bigger chance that miner will burn gpu than gamer.
My kid is playing on 1080ti ( I have no intention of getting him better until he gets better in school) for 5+ years, card was cleaned few times in that time, thermal paste never changed... No issues with the card, I think chances for the same card to survive 5+ years of 24/7 mining, barely any cleaning... are slim
I have a lot of GTX 1060,1070, 1080 and RX 470-480 video cards that have been mining for more than 5 years. The fans are broken. Chinese fans from aliexpress are of very poor quality and work for 3-4 months, so I use standard 80x80.
