That's not something that can't really be answered as different versions (brands) have different "sub" versions too. You could buy a card from almost any brand and it could come with Samsung, Hynix, Micron, which can make quite a difference, especially if you plan to overlock. Beyond that there's always silicon lottery, and a huge part of temps will be environmental. Are you running open frame? Desktop case? What's your ambient temp? What additional fans, if any, are you using? etc.
With that said, generally speaking your higher end (more expensive) cards are going to be better. You can get binned examples from brands like Red Devil but expect to pay more for them which extends your ROI/break even point. BUT depending on your electric costs it could, in some instances, be better to get two cheap cards vs one good one. Endurance I wouldn't worry too much about, worry about getting a good warranty policy as endurance is also down to luck. One card might last a few months, another from the same batch could last years.
I'm running a few 12x GPU rigs here, all open frame but physically placed in a 42u rack (so the cats don't get sucked into the fans) with a mesh front. The 5700 XT's I'm running are all Red Devil as Amazon had a bucket of refurb's at one point for <$300. The RX 570's are all ASRock. I don't let any card get above 65c using hiveos auto fan but it's usually considered safe to 85c. Keep in mind your memory will likely run much hotter, as the 5700 XT will keep boosting until, I think it was, 106c mem. Might have even been 110c, I regularly show 104c on mem. So that's going to run hot no matter how you cut it because that's just how the thing was designed. Ambient temps are never above 75F.
But yeah, there's no exact answer as a lot of it just comes down to luck of the draw. From the silicon lottery to memory type. Buy it from a reputable retailer and you might be able to do one swap if you don't like the card you got but few, if any, are going to let you keep swapping indefinitely. So there's always going to be some luck involved.
