they are the ones off nvidias site in the file name it says whql and they are version 270 something so that's good and the gpu runs 75 c but I heard that is ok. It is getting lower now coming to an idle at 64c which I don't see as a problem
no just recently it started but I updated the driver a few days before the fan so I don't know whats to blame. I looked around and found some people talking about the same sort of issue but they have gtx 570s and stuff so I don't know if it is the same driver. The post is from a few days ago
