Well I was on a 3070 Ultra for 272 day, no issues. Been on my 3080 FTW3 Ultra LHR now for over a month. Made sure I had the proper power supply for the 30 series as older designs to super cheap psu's that have not been upgraded for the spikes are known to kill the cards. Believe that is where a lot of the issues stem from. See it all the time, older psu's over two years old, older psu quality models that sat on shelves to put into machines eating cards before they critically fail due to the spikes to just killing the cards in general as they did not get upgraded to handle the massive voltage spikes of boost clocks. Last week alone I saw that happen not just with EVGA but multiple brands including a very nice white ASUS 3080 TI model an old bequiet power pro 11. Including some older quality Seasonics, to even some older corsairs. If that tells you anything. Going to get a 30 series card? Be sure you have one of the latest quality psu's up for the task or it will probably come to bite you.
Tech changes, remember when one of the new motherboards came out and the old psu's didn't play nice with them and caused issues? Same thing stuff is always moving forward. Those saying during games 450w on an air cooler, you do know this one particular game due to bad coding bypassed all safety features of the card's firmware and software as it sent the cards into a state worse than benching/folding/mining/rendering, stuff is going to get hot and under that kind of load with all the safeties bypassed bad stuff will happen especially if you do not keep it colder. Its sort of why say Quadro's exist to miners who take these gaming cards always undervolt and underclock them, or you have enthusiast who go overboard to keep them cool be it for gaming or someone who works and plays on thier cards. Like me I never let any part of my card hit or go above 70c. That is the other issue, bad coding in games that sends cards into overdrive it was not just nvidia it was doing it to, it was also AMD's latest and greatest.
