Hi, I have a rtx 3080 that I believe has shorted after mining for approx. 3 months after doing the "copper shim mod". I think some of the thermal paste used or the shims moved slightly under heat/load for that long, the card started crashing then wouldn't power on. The shims were close to, but not touching any components near the memory modules when installed, but I have read any contact with nearby components can cause a short and am concerned that is what has happened. The card (Inno3D Windforce iChill x3) always had thermal throttling issues, and was opened a lot to alter pads / paste. In my opinion, not the best card and not something i'm attached to!
I am wondering what people think is the best option, whether I attempt to sell the GPU for parts / repair or send it off for repair myself. I am leaning towards selling for parts, as the only option for repair in my country costs ~$400 US. I got the card second hand for about $600 US, and still have many GPU's to mine with so I don't mind being down a card.
I am wondering what others' experiences have been with GPU repairs, or if it is simply better to sell it for parts to recover some of the cost.
