I have recently bought a used XFX RX 580 8 GB GPU. It’s not older than 2 years. Cannot be sure if it has been used for mining or gaming, but I got it with the gaming BIOS, which is what I use it for.
So first thing I did is I opened it up, cleaned the remaining of the old thermal paste and applied new one. I did this on multiple cards (of same type and some GTX 1060), but it’s this particular one that gives me headaches.
After some time (less than 2–3 weeks), my PC suddenly switched off during gameplay. That happened again soon and I decided to open it up and look for signs. I disassembled the GPU and found out that there was barely any thermal paste left on the chip and the heatsink. I applied the thermal paste again and reassembled everything again and continued using my PC for gaming.
Now the same issue, exactly as the last time, happened again. Again, it was after less than 2–3 weeks. Now I’m worried that my GPU is overheating and melting the paste off quickly. I’m curious what might be causing this.
Could it be a bad thermal paste quality? Is it just something wrong with the GPU hardware/heatsink?
All the other parts in the PC are new, bought freshly from the shop, so I wouldn’t expect it has to do with any of them. I have 2 fans on my case, 1 as an intake and 1 as an exhaust. I have few of these setups built and this one particular is the only one giving me troubles.
The thermal paste I used is a low quality one I guess: https://www.amazon.in/HT-GD660-CPU-Thermal-Grease-30g/dp/B01LW8TKX6
