So i sold a friend of mine a 2048sp rx 580 for a cheap price. The card was released in October 2018. I took the card apart last time and cleaned it. I'm not sure if it was used for mining because the bios was normal but it was dirty. I cleaned it and replaced the thermal paste. In my friend's rig, i configured the fan curve so that it never reaches 80C. Mostly 60 to 70C with around 55% fan speed. Power draw of the card is around 120w to 130w on load. He doesnt game every day so mostly the card will remain idle. I know there's no way to be certain but how long will the card last? Physically i mean before breaking down. I'm not talking about it being obsolete. Not sure if it's relevant but power supply is cooler master masterwatt 550w 80+ bronze. Oh yeah, i used the card myself for a month before and everything wS running fine. No artifacts etc
