XFX HD6970 3-way CFx & HD6950 CFx review

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.

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.

Due to the (really) close proximity of the cards in our 3x configuration, the ambient temperature rises significantly and the fans speed up to maintain the temperatures. We will delve into noise characters more on the acoustics performance page. High levels of case airflow are a must.
