Hmm .. received my Inno3D GeForce RTX 2080 Ti X2 OC last week. Stock with no manual OC or anything daft.
Works fine until I stress it. Default fan profile gets it up to 84c ... manually setting fans to max (too bleeding noisy), drops to 64c or so. But .. keeps crashing

Usually crashes whole PC but when it does not, these are the recorded temps

RMA it only if you have tried the latest nvidia drivers even though they're trash.
A new stock gpu should never overheat especially with the stock cooler at 100%
If it gets too hot it should throttle down, not crash. Sounds like either bad thermal connectivity or bad overclock by inno3d
