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

 

 

 

 

 

 

 

 

 

 

 

 

 

Sapphire's Vapor-X cooling solution pays off when it comes to the temperatures delivered by this card. Under load at both stock and overclocked it is cooler than the reference cooled XFX Black Edition. The overclocked temperature difference between the two is only three degrees when overclocked, but the noise difference is where the biggest bang for the buck occurs with the Vapor-X running much quieter when the fan speeds are ramped up to 100%.

While the overclocked results are seemingly not that impressive as far as temperatures are concerned, the difference when running at stock speeds with vBIOS-controlled fan settings is very much so. The Vapor-X cooling delivers a 12 degree improvement over the reference cooling solution on the reference cooled HD 7970.
