My edge temperatures are fine. In fact, everything but the hotspot is not a concern and temperatures are good and this is in extended 4K gaming scenarios (Baldur's Gate and Starfield). I have just asked the vendor for an RMA but I'm really not sure. Maybe the card is just meant run that bit hotter (on hotspot) as a custom model.
Your hotspot is defiantly a problem, your edge can still be much better but is nothing to worry about.
If you have a liquid devil you should least be getting about same temps as me with PTM7950 on unleashed bios no undervolt or anything, powercolor does not use to little thermal paste if their cards have issue its likely pumpout issue, they need to use paste that does not have pumpout issue or switch to PTM7950 honeywell sells in big batches so for some one like powercolor getting PTM7950 should be easy.
Hopefully they switch to it on nextgen cards, i know there are paste out there that last a lot longer then the stuff powercolor uses, but 3 months is really bad which was time it took for me i think, then 1-2 weeks after repaste with MX-4 2 times 3e time i just bought PTM7950, there was a lot of information online that it would not work well cos watercooled card does not get hot enough for the PTM7950 to melt, it gave me better results instantly, normally it perform slightly worse then melts then gets better and better, and pulls ahead of liquid metal.
The advantage of PTM7950 is that it melts at 45c and gets solid below 45c.
