Ever used DI or ln2/lhe for that matter?
It was the last slot that pulled out...even a glacier ln2 or lhe bench session would never even remotely get the lower slot cool much less dry ice.
This is actually my system, my photos of stuff i have actually and personally done..so i can speak from experience and not hypothesize...
Running components on board keep even slot 1 warm unless you have a gpu on ln2 as well which he did not.
Shoving a board outside in winter as many have has never caused pci slots to rip out of a board.
Hell ive poured dry ice and ln2 directly on board even piled it on...no issues..
It clearly had a defect as like any vendor could have.
Nobody or company is perfect...
