I overclocked my GTX970 to 1550mhz core and 1800mhz memory. My question is 63-65c okay to run for 5-6 hours streight or even longer during gaming? Fans are starting at 60c, and they are 40% I think later on. So just wondering, I wouldnt like to mess up with fans if they are made to work that way. It's MSI.
