Hi, I wanna know whats the best fan settings for my graphic card using MSI Afterburner or is it best to leave it at Auto. I am using a Gigabyte GTX760. I played around with the settings a bit and made it go 50% speed when its at 50C and 55% speed when it hits 65C. What's the optimal settings for it? I am currently hitting 58-61C on BF3 with the current settings. Is 50-60% speed too high and will it shorten my card lifespan? I never hit 50% speed before when it was on auto.
