Hello!

I have a 3080FE, 12 months old. I bought the 2mm Gelid Extreme pads for the front side and I managed to reduce mem temps by 20c, the gpu die got hotter so I reopened it and tried to squish the pads a bit more and repaste the gpu. After several attempts I could not manage to reduce the die and hotspot temps, eventually it stopped working and now there is no video signal and no leds, I just see the fan spinning but they are not at 100%. I tried to repaste the die again, cut the excess of thermal pads due to me maybe squishing them too much,I used a different mobo to make sure I did not damaged the pci slot, I used a different psu and even a different 12 pin cable adapter, still no signal and the gpu is cold. I inspected the pcb, I cannot see damaged or missing components, the 12pin connector is stiff.

I might have unscrewed the leaf bracket screws unevenly, causing the gpu die to bend or to allow micro air bubbles to get in? Would be the next thing to do to just send it to a specialised reballing laboratory and see what I get? The pcb is not 100% clean after all those attempts so I wonder if the kryonaut paste would be conductive enough to get a shortage. I will try to clean it a bit, try the 1,5 Gelid extreme pads instead of the 2mm that also started to crack after all these attempts, but I doubt it will solve the issue.

I also cheched a couple of resistances with the multimeter and probed the first and fourth last pins of the pcie but I get similar values to other people.
