RTX 3090 FE HELP! GPU overheating.

@TaKeN My calipers measured the die at 22x26mm but I ended up eyeballing the cut. Held the piece upto the die snipped a small cut with mini scissors before taking a big scissors to finish the job.

Ah interesting! Wish I knew that before ordering

Silicon that the die is made of can just deteriorate and start to get hotter gradually. This would mostly be caused by use. Mining is suggested as the biggest cause because it's 100% use all the time. Gaming is harder on the gpu than mining though. It could even be a driver update has made it so part of the gpu is getting used a little more. If it was overnight that the change occurred I'd be more heading towards a driver update. It wasn't too long ago that nvidia drivers had caused some gpus to burn or go on fire.

I rolled back the driver update to see if that was the cause. The version I had (which was the latest at the time) when the spike occurred was installed for about a week or so. And I was still gaming on it during that timeframe. So I guess it could be that there was a gradual deterioration just suddenly crossed some threshold?

have you removed and replace the backplate each time aswell? If so I take it everything was fine back there.

I think you meant if I put the same stock backplate back on, in which case yes. It seemed all fine to me, couldn't see anything that stood out to me tbh

Final update for anyone still interested/following this thread.

The ptm7950 did improve the temps albeit only by 3°C in the end. Fan's were still going crazy. So I ended up a getting a 3080 to replace the 3090. I'm going to sell the 3090 to recuperate some of the cost of the replacement GPU.

Thank you to everyone who commented to try and help me diagnose the problem. I really appreciate all the inputs!
