Testing:

Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 2.5, with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1200 using 8xAA and a 5-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.

Settings

  • Monitoring with MSI Afterburner
  • Unigine Heaven 2.5 1920x1200 8x AA

Lower = Better

 

Equipped with the Double Dissipation cooling system, the XFX HD 7970 Black Edition delivered significantly improved cooling over the reference cooler at stock speeds, both at idle and under load. When overclocked, the tables are turned somewhat. The XFX overclock was achieved with a voltage increase, while the reference card was not overvolted. The additional thermal load is dumped into the chassis, leading to temperatures on par with the stock results. On the other hand, the reference card gains the benefit of discharging the load out the back of the case.
