Keep in mind that Bioshock Infinite, while a beautiful game, not too demanding. A GTX 760 easily maxes it out at 1080p. I just tried to check the RPMs, unfortunately nor GPU-Z or Precision X are giving me an RPM reading. And since I'm OCD before I even powered on the on the card I changed the TIM, and I recall the fan connector only using two wires. So there is no RPM signal.
