My GTX is always arround 55-60C while on the internet and I'm really afraid of it burning or happening something of that sort. It has happened to me when that I'm playing ut suddenly shuts my computer off and leaves a light burning smell and when I put my hand on the metal part of my desktop it is really hot... I haven't tried seing the temperature while playing because today the scene where it randomly shuts off happened and I don't want my GPU burning. I don't know if 55-60C is normal when surfing the internet...
