If you manage to kill a GPU in less than 5 years of mining on it, you're doing it WRONG.
I have quite a few cards that have been mining (or running the DNet client, which is also crypto work and JUST as intensive to the GPU) since the LITECOIN GPU mining days in 2013/2014 that are STILL mining away today.
Do quit spreading the "mining kills cards fast" FUD lies.
I think it all depends on if you can keep them cool. How many fans need replacing/rebuilding after 12 months on GPU's. I've had a few that I had to replace fans because they just wore out. I did kill 1 7950 because the fan went out and I wasn't monitoring it and it ran for a long time at high temps in the summer. Heat and GPU's don't mix well.
Yeah, fans definitely seem to be the weak link here. My Zotac mini GTX 1050 Ti worked just fine playing MechWarrior 4 Mercenaries for about 11 months (and yes, this 12+ year old game was demanding enough to cause the fan to spool up at times), then 1 month after I started using it to mine the fan died. Likely the fan was "one step away from the grave" right from the factory, but the fact remains it actually died not long after I started mining.
