Temperatures

Temperatures look reasonable given the low cost heatsink design.

GPU Temperature Comparison
	Idle	Load
NVIDIA GTX 670	37°C	82°C
ASUS GTX 670 DirectCU II	38°C	74°C
Palit GTX 670 JetStream	30°C	75°C
ZOTAC GTX 670 AMP!	35°C	70°C
NVIDIA GTX 680	45°C	85°C
ASUS GTX 680 DirectCU II	33°C	70°C
AMD HD 7970	45°C	78°C

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 Profiles

Modern 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.

	Core Clock	Memory Clock	GPU Voltage (measured)
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	915-1084 MHz	1502 MHz	1.030-1.175 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.
