I have a Gigabyte Low Profile GTX 750 OC 2GB and the fans run @52% max while the GPU temp goes to 80 degrees while gaming. I can manually change the fan speed but why doesn't the GPU automatically make it faster? And what else can I do to keep my GPU cooler? I don't care if it makes a lot of noise (the fans). I've heard that the higher the temps , the shorter the life of the GPU. Some people say this is normal but some say it's too hot. I'm confused. So any suggestions?
