Thermal Images
We also snapped a few infrared pictures at idle, at regular clocks and at overclock clocks as you can see here. At idle, the center of the card gave us a 28.3 degrees Celsius reading.
While gaming at stock clocks, that increased to 38.2 degrees Celsius and the top exhaust of the card showed 66 degrees Celsius.
While overclocked, temperatures dropped slightly due to the higher fan speed configured (50% at stock, 80% while overclocked), yielding 37.8 degrees Celsius and 57.6 degrees Celsius.
