Sorry for my English in first place. So 3 weeks ago I bought used 1080Ti INNO3D iCHill X4. Seller came to my house, I tested the card in many games and run few benchmarks and stress tests and everything seems fine so I bought it. Later I realized that card is running INSANELY HOT, 82-86degrees while gaming and from the posts I found this seems normal for this card, it's actually hotter than reference card. So I decided to UV the card, I did that to every GPU I owned. Temperature then didn't go past 73 degrees. Some time later I decided to change thermal paste and see if it will help and after changing the paste the temperature actually went up so I thought maybe I put too little. I took off the cooler and indeed there wasn't a lot of the paste on GPU so I wiped the previous paste and applied again thermal grizzly the best I could. I had problems with putting the cooler back on. I lined up the cooler with the holes on PCB perfectly but I coudn't screw it back. I always treat the GPUs like bar of gold and this time was the same. After spinning the screw for some time I heard strange sound and GPU bent a little bit. I got very scared and started to loosen up this screw really fast. I think it's terrible cooler design because only 4 screws hold entire 2.8 slot cooler connected to PCB. Meanwhile FE card has like 20 screws holding the cooler so GPU just can't bent. Something was wrong because the paste on GPU didn't even touch the heatsink. I took the cooler off and managed to put it back on without problems at second time. After that I started getting stability issues. Games started crashing on stock settings and would only work after card was undervolted. I took the cooler off again to check for any potential damages (I was very careful all the time) but the card seemed fine and there wasn't any bent. Repasting again didn't fix this issue. Card needed more and more voltage on UV each day to don't crash. Today PC isn't booting with the GPU inside anymore and LED for GPU error is lighten up on motherboard. Do you think card was defective in first place or I could break something while trying to put the cooler back on? The card is from INNO3D and was bought in German store which has been closed over a year ago.. I still have the invoice however... I contacted the INNO3D already but they're really slow at responding for emails, it usually takes them 1 full day to respond for 1 email.. I'm just scared the might don't help me with the warranty because the store no longer exists...
