Temps when new:

 
 
Temps after a year:

 
Those temps were even after a repaste. I was hitting 95c on the hotspot before the repaste. So it's alot better, and within spec now, but is definitely getting hotter as time goes on. Fans could be going out, but the memory temps haven't increased at all, so maybe the fans are ok, but the die is getting worse.
 

Card should last longer but you post reeks of mining type abuse
you may need to get a larger cooler

A larger cooler such as?

dang, even after repaste,
 
leakage current in the cpu might be increasing?

Cool GTX

Something is definitely going on. Could be that, but I don't really know.

RMA, might be your next step, especially if the temps go backup to mid 90C range, at the hot spot?

Yeah, I may have to use the 4 year warranty that the card has if I can't keep it below 95c on the hotspot.

could try Honeywell PTM7950 as a last resort or liquid metal if neither of those two helps yup card is on its way out. I was thinking of trying PTM7950 once my tim degraded but it's been cool as when I got it almost a year ago at load and idle.

Thanks, but I’d like to stick to non conductive stuff. I’ll try some thermal grizzly kryonaut next. Currently have some corsair tm30 on it atm.

If you opened your RTX 4090 to re-paste it you might have voided the warranty.
