So recently my RoyalAce R9 290 started to heat up significantly under gaming loads that it did not used to have issues with, like Overwatch. It would get up to about 85-88C on the reported core temperatures and textures/effects would start to show artifacts, like neon colours on textures.
I tried checking the cooler and replacing the thermal paste, since the card is now about 28 months old so I did not think I had any other recourse. Does Club3D consider replacing thermal paste to be breaking the warranty?
After replacing the thermal paste, temperatures dropped into the high 70s for a time, but they have been climbing again and the texture corruption does still appear when the card’s reported temperature gets to around 79-83C. I ran a gaming session with HWInfo in the background and it was reporting VRAM errors during this, so I think it might be the memory that’s developed a defect?
Can anything be done at this point? As I said, the card is past its retailer warranty at this point, and was working fine up until now.
