PowerColor Devil HD 7870 Testing:
Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 4.0, with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1200 using 8xAA and a five-run sequence to run the test, ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card's BIOS for the stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will involve a 20-minute cool-down, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.

- Temperature measured in degrees Celsius
The temperatures delivered by the Devil HD 7870 are pretty impressive for the cooling solution employed on this card. At stock and overclocked idle speeds the Devil HD 7870 was the coolest card in the comparison. Under load the card was one of four cards less than 70 °C at stock speeds and reached 63 °C under load when overvolted and overclocked. Warmer than you would think from this card but running the maximum allowable voltage does have that effect on cards when under load.
One thing I noticed was that the time it took to reach minimum temperature from maximum temperature was less than a minute, showing just how efficient the cooling solution on the Devil HD 7870 is. The one thing that was a concern was that when I ramped up the fan speed I would get an incessant rattle from the shroud until I held it in place. After my tear down I found the culprit; a few loose screws holding the shroud in place. Overall an easy fix.
