XFX HD6850 Black Edition Review @ 1ghz : World First Exclusive!

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.

The customised cooling solution on the XFX HD6850 card delivers great results although it is running 4c hotter than the standard clocked version. Furmark reaches a peak of around 74c when fully loaded.

Return to ambient is a feature we have recently added to our reviews … we measure the time it takes for a solution to return to idle temperatures, immediately after full load. The faster the time, the better the cooler – for example a Noctua NH D14 cooler will return an Intel processor to idle temperatures much faster than a reference cooler. This is a good indication of how quickly a heatsink can dissipate heat.

The cooler takes 18 seconds from extended Furmark load to return to an idle state. This is a capable cooler considering the enhanced clocks.
