I still find that on the high end. I know the cooling for the XC3 is somewhat inferior to the FTW models from EVGA, and tend to run warmer overall. My Asus TUF 3090 never goes above 65c for the core temp, and I’ve never seen my memory junction peak higher than 90c while gaming, but usually hovers in the mid 80s. That’s with a slight +70 Mhz core offset and +500 Mhz memory overclock.
I’m not saying there’s anything wrong with those temps, so long as you’re not thermal throttling.
