My RX 480 ASUS ROG STRIX 8GB OC is overheating. but not just overheating, it is getting to over 90 degrees!!! Even when just loading a damn game it gets to 78. when it goes over 90 degrees it shuts down my whole pc by just cutting the power instantly. it happens in any game, and started happening about 2/3 months ago. I tried all the obvious things like taking it out, dusting it off, checking if all fans spin. The weird thing is, even when manually overriding the fans to 100%, it gets up to 80-88 degrees. I think I just have a malfunctioning card. I'd be happy to answer any questions and hope to get some possible scenario's!
