Temperature Testing
Since video card temperatures and the heat generated by next-generation cards have become an area of concern among enthusiasts and gamers, we want to take a closer look at how the Radeon HD 5800 series does at idle and under a full load.
ATI Radeon HD 5870 Idle Temperature:
At idle the Radeon HD 5870 had amazingly low temperatures that shocked even us. When we first looked at the Radeon HD 4870 in June 2008 we found that it had an idle temperature of 74C. The new Radeon HD 5870 idles at just 38C, which is impressive considering how fast this card is and that this is a reference heat sink. As you can see from the screen shot above, the idle state of the Radeon HD 5870 drops the GPU frequency down to just 157 MHz and the memory down to 300 MHz to help conserve power and lower temperatures. AMD has nailed idle temperatures on this series from the looks of it.
ATI Radeon HD 5870 Load Temperature:
We fired up FurMark and ran the stability at 1280x1024, which was enough to put the GPU at 100% load in order to get the highest load temperature possible. This application also charted the temperature results so you can see how the temperature rises and levels off, which is very nice. The ATI Radeon HD 5870 maxed out at 85C, but fluctuated between 83C-85C once it leveled out. The fan on the ATI Radeon HD 5870 video card was left on auto during temperature testing. The fan never got over 35% during testing, so manually increasing the fan speed in CATALYST Control Center would help lower the temperature some more if you don't mind the extra noise.
