The longevity is incredible.I almost wish one of them would konk out so I can get an M series, but then I wouldn’t be on a 5k iMac anymore, which would suck. Love these machines.
Dropbox would fire up to do massive walks of the filesystem tree and the fans would take off. I think the thermal interface material on the GPU got cooked at some point. It would be a relatively easy fix, for me a couple of hours, but I chose to fix it with an M1 MacBook Air.
