But I used my Radeon RX 6700 XT for mining nearly 24/7 for about 10 months (between purchase and when it paid itself off), while using it for gaming in between (I'd obviously stop mining). It ran around 65°C during that time. Very low core clocks, but memory was run at close to the maximum recommended speed by AMD's Adrenalin software. At least so far no signs of any problems.
