Diamond, Sapphire & XFX AMD Radeon HD 6870 Video Card Roundup

Temperature Testing

We fired up FurMark and ran the stability at 640×480, which was
enough to put the GPU core at 100% load in order to get the highest
load
temperature possible. This application also charts the temperature
results so you can see how the temperature rises and levels off, which
is very nice. The fans on the video cards were
left on auto during temperature testing. When we hit the space bar to stop the rendering the
temperature dropped.

The XFX and Sapphire Radeon HD 6870 peaked at 77-78C and the Diamond Multimedia Radeon HD 6870 XOC peaked at 82C. It looks like the mild overclock on the Diamond card caused it to be 4-5C hotter at full load. All of the cards had idle temperatures around 42C.
