Temperatures were measured after 10 minutes of load under three scenarios: Furmark GPU stress test, Unigine Valley looping at the Extreme HD preset and desktop idle. GPU-Z was used to record the maximum temperature, fan profiles were left to their default behaviour.
Delta temperatures are presented below to account for small fluctuations in room temperature, but for all the testing present in this graph the temperature ranged from 21.4 to 23.5 degrees Celsius.
Temperatures are absolutely stellar, in the high 50s for a standard room temperature environment. The cooling solution is over-engineered for this GPU, but that's certainly nothing to complain about.
The hottest part of the card was in the low 50s which is a very safe temperature given this card was going through a Furmark torture test.
