PowerColor Radeon HD 7870 Myst Edition Crossfire 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.

 

Settings

  • Monitoring with MSI Afterburner
  • Unigine Heaven 4.0 1920x1080 8x AA
  • 5-run sequence
  • 20-minute idle duration
  • Temperature measured in degrees Celsius

 

 

 

 

 

 

 

 

 

 

 

 

The temperatures delivered by the PowerColor PCS+ HD 7870 Myst Edition are not that bad overall when you look at what's under the hood. However the GTX 660Ti combo is cooler overall. This margin in the thermals can be explained by looking at the power consumption results where the HD 7870 Myst Edition is much less efficient than the GTX 660Ti combo, leading to higher overall average temperatures. Spinning the fans up to 100% does have the adverse effect of raising the noise signature of the pair of Myst Edition cards. Outside the chassis the noise is not bad but is audible.
