Our noise testing page showed incredible low noise levels emitted by the card in both idle and load. Normally you'd expect temperatures to be high, but that's not the case. Looks like the ASUS DC II cooler is the perfect match for the GTX 670. Temperatures are great.

Important: GPU temperature will vary depending on clocks, voltage,
cooler design and production variances. This table just serves to provide
a list of typical temperatures for similar cards, reached during TPU review.
Clock ProfilesModern graphics cards have several clock profiles that are selected to balance power draw and performance requirements.
The following table lists the clock settings for important performance scenarios and the GPU voltage that we measured. We measure on the pins of a coil or capacitor near the GPU voltage regulator.
|GPU Voltage |
|Desktop||324 MHz||162 MHz||0.99 V|
|Multi-Monitor||324 MHz||162 MHz||0.99 V|
|Blu-ray Playback||324 MHz||162 MHz||0.99 V|
|3D Load||1058-1293 MHz||1502 MHz||0.987-1.175 V|
The card uses NVIDIA's dynamic overclocking mechanism, which means it will dynamically adjust clock and voltage based on render load, temperature and other factors.
For the graph below, we recorded all GPU clock, GPU voltage combinations of our benchmarking suite for the 1920x1200 resolution. The plotted points have transparency, so they can add up to indicate more often used values. A light color means the clock/voltage combination is rarely used, a dark color means it's active a lot.
We see a huge range of clocks and voltages which show that ASUS did some extra tweaking to their settings. Also maximum GPU clock is extremely high with 1293 MHz, which is higher than what we have seen on any GTX 670, 680 or 690. This seems to be the key to the amazing performance of the ASUS GTX 670 DC II.
