I was playing the witcher 3 today at about ultra settings and hair works turned off when I noticed that the Saphire logo led turned red and I imediatley turned off the game. Is that a bad thing? I heard it only turns red when it is overheating and is about to fry itself. Since then I changed the fan speed from 20% to 45% and it seems to keep the card under 70c so far. Any ideas what makes that have caused it?
