Well most new Graphics Cards don't spin the fans until the GPU reaches a higher degree on heat, example my GTX 1060 6GB Strix ROG only starts to turn the fans above 55c degrees, and its spin the on 40% until 62c and actually on every possible benchmark and overclock my card don't go more than 65c with max fans on 42%. Try give it more load, give the GPU a stress test to pass those 58c or above 65c and check the card if then starts to spin the fans above 65c, if you see the GPU goes fast to that temp like 65c and fans are still not spinning, well that might be a some hardware issue.
