Yes, until now I believed it was only AIB cards that had exhibited this issue and from that I inferred it would be those where the "chassis" of the card isn't properly attached to the rear bracket allowing a large degree of flex/sag.
It was only that someone earlier commented 4090FE cards were also cracking which surprised me and started me wondering how and why.
Incidentally, in that northridgefix video, the number of Asus cards was shocking.
There's apparently been a couple of fe cards it's happened to. But I think third party cards are more vulnerable. The FE card is basically a metal box with a very small pcb inside, most of the third party cards are long pcbs with a heavy heatsink hanging from them. They're going to be more prone to flexing the board a lot and potentially cracking.
