XFX Radeon HD 5970 Black Edition Limited 4GB in CrossFire X 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. These results are taken with the system built inside the Lian Li 8GIB Chassis.

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.

Our temperatures show that XFX have managed to improve on the reference design with their custom PCB and cooling solution. Despite the large overclocked settings, the cards run cooler than the reference HD5970 . This is particularly noticeable when running Furmark as the ATI board would peak around 90c whereas the XFX solutions were running 8c cooler.
