Cooling and noise production
We measured the temperature after two benchmark rounds of Metro 2033. The relatively small cooler doesn't keep the temperature as low, its 70 degrees is the second-warmest GTX 670, right behind the much higher clocked ASUS GTX670-DC2T-2GD5.
The cooler is also noisier than we're used to, something that's probably inevitable due to the size. Still, many other cards are even noisier.
