The hot spot on my reference 5700 reaches 82c gaming at stock. This is in an old HAF 912 case. But, then again, my GTX 1060 always went 83c gaming. The thing is the fan at stock is set to max out at 39% no more. At 41%, which is still inaudible, that temp does not see 80c.
Point been? We do not have "hot spot" value from Nvidia to run comparison how hot they run there. So Core temperature is what we should bother then, which are comparable the Navi and any Nvidia core temps. When Nvidia provide us with Hot Spot values sure, lets start comparing it.
Also kinda pointless trying to compare apples & oranges of a GTX1060 in HAF 912 without any further other indication of room temp, how many fans the case has etc, on how hot a 5700XT can be.
You make wild assumptions.
