Temperatures

Temperatures are low thanks to the triple fan cooler. Combined with the low noise this is a perfect combination.
Load temps are well optimized and look like they have been designed to not exceed 80°C, which is a good thing, as NVIDIA's dynamic overclocking mechanism takes temperature into account and lowers maximum boost clocks by 13 MHz each 10°C.

GPU Temperature Comparison
	Idle	Load
Palit GTX 680 JetStream	33°C	78°C
AMD HD 7970	45°C	78°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	0.97 V
Multi-Monitor	324 MHz	162 MHz	0.97 V
Blu-ray Playback	324 MHz	162 MHz	0.97 V
3D Load	993-1163 MHz	1575 MHz	1.030-1.180 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.
