by techPowerUp! (Sep, 2012)Temperatures are super low due to a high fan speed, but this offers no tangible benefits to the user - a quieter fan would be better.Price-wise, the KFA² GTX 650 EX OC comes at NVIDIA's reference design price, which is nice given the custom cooler and small overclock out of the box.
