The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 25c – a comfortable environment for the majority of people reading this.
Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.
Exact same results as the other cards we have reviewed before. Both cards generally maintain an average of around 73-75c when gaming, which rises to over 80c when Furmark primed. The 5th generation Vapor Chamber is actually pretty good considering the performance levels.
We then measured the temperature changes when running both HD6950 and HD6970 in our Crossfire configurations.
As the HD6970s in CFx three way are so close together, the heat levels rise significantly. The fans speed up trying to maintain sub 100c temperatures. We will look into the noise levels later. In closing however we would strongly recommend a high level of case airflow with a CFx three way configuration.Sapphire Special Edition HD6970 and HD6950 CFx Multi Screen Review,
