HD 7970 3GB DirectCU II Testing:

Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 3.0, 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.

Settings

  • Monitoring with MSI Afterburner
  • Unigine Heaven 3.0 1920x1200 8x AA
  • 5-run sequence
  • 20-minute idle duration
  • Temperature measured in degrees Celsius

 

 

 

 

 

 

 

 

 

 

 

 

 

ASUS's DirectCU II cooling solution delivers outstanding cooling results when under load. The idle results are strangely not as impressive as the load temperatures, though. Compared to Sapphire's Vapor-X cooling solution, the closest direct competitor's card in the comparison list, ASUS DirectCU II delivers a load temperature bonus of 5°C stock and 4°C overclocked – around a 10% improvement.
