Spot or dent on gpu

[PotatoWizardNL]

Hi I have a problem with my graphic card

I have removed the heat sink and the old thermal paste and put in some new paste

Now it was some old paste I had left few years old when I put everything back together and back in the pc it immediately went to 80 degrees and restarted the pc

I've removed the heatsink again and there was this spot or scratch mark or dent on the gpu I'm waiting for new thermal paste but is my card dead now?

Its possible, yes. But I would think its more likely you didn't use enough paste? It would be weird that it shot up to 80 instantly.

Well past 80 around a 100 under load and then black screen and pc restart the whole gpu was completely covered with paste I would think perfect but maybe it was a bit to little tomorrow I get corsair tm30 and ill put on a good blob of that and try again

Oké here is the update. 

I've put on a good blob of thermal paste corsair tm30 and got every thing back together. 

I've tested for a minute on furmark and it didn't crash immediately so that's improvement. 

I'm really glad it's not dead for now I'll do some more long term testing but it looks to be back to normal

My guess is that some kind of contamination got into the thermal paste.  Either in the tube or while applying it.  When you cranked down the cooler it caused that spot and still wasn't making good contact.   It would explain both the temps and the spot.

oke now ive done some testing and some gaming and it seems to be back to its old self

now that wasnt the greatest thing because it keeps throttling around 60°C 

and thats why i wanted to change the thermal paste but it didnt do anything maybe just made it worse.

but now i was thinking what if i polish that little dot of the gpu what will happen maybe you guys have tested this before or something

cuz i dont want to screw up my card

 

ive also attached a file from gpu-z with clockspeeds and everything

I cant tell from the picture .. if that thingy there is an outwards going blob then you are on the safezone if that is an inwards going crate then your GPU is damaged if its still working then you are lucky but its definitely damaged I would expect weird behavior or instability at some point or when you stress it to 100% the best case scenario is to have performance loss.
