Power, Temperature and Noise
Slightly faster than the immediate competition means slightly higher power consumption, too. Not a lot in it, mind.
GamingPro Premium may ship with three fans, yet the smaller overall profile and build quality intimates that cooling performance isn't going to be top-notch. This is reflected by an in-game temperature of 75ºC, which is barely any cooler than Nvidia's Founders Edition.
Under load, the Palit card isn't drastically quieter than reference, either, though it does have the benefit of being practically silent when idle.
