Temperatures

Considering that this is a passive design, temperatures are very good. I also tested in a case which has absolutely no airflow, and here, the card would reach the 83°C temperature limit at which Boost clocks will be reduced. Clocks went back to base clock, which is still decent, and stayed there even during heavy gaming - no overheating. So your case will ideally have a little bit of airflow for the hot air to go somewhere, but you definitely don't need a lot of airflow.

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 is used in those states.

The card uses NVIDIA's dynamic overclocking mechanism, GPU Boost 3.0. It will dynamically adjust clock and voltage based on render load, temperature, and other factors.

For the graph below, we recorded all GPU clock and GPU voltage combinations of our 1920x1080 resolution benchmarking suite. The plotted points are transparent, which allows them to add up to indicate more often used values. A light color means the clock/voltage combination is rarely used and a dark color means it's active more often.
