Hello, one month ago I bought this GPU (sapphire 290 tri-x). I have recently discovered some issue with the card.
The issue I have is that the GPU's fan will sometimes go up to 100% (almost 4000 rpm). This can happen anytime even when computer is idle the fans can jump up to 100 % then maybe go down to 60 % then up again to 100 %. It keeps doing this for a minute or so, then it goes back to normal fan speed 20 % (1500 rpm). But the tempetures are always very low.
