The Maximum Operating Temperature of the RX57xx series GPU cards is 110C.
The RX57xx GPU cards have several Thermal Sensors throughout the GPU card. If any one of those Thermal Sensors reaches 110C the GPU card will automatically start to throttle to lower the Temperature to 110C or below.
So your Temperatures are fine in respect to the Maximum Operating Temperature of the GPU card. All well within Temperature specs for that GPU card.
