PowerColor Radeon HD 7790 Turbo Duo 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.



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












Looking at the idle temperatures specifically, PowerColor's Turbo Duo Professional Cooling System is cooler running than the Sapphire Dual-X solution. Low idle speeds are nice to look at but the real meat of the discussion comes from the load temperatures. PowerColor's single heat pipe solution delivers cooling results six degrees higher in both the stock and overclocked testing. Even that much higher than the Sapphire version, the HD 7790 Turbo Duo is still at least five degrees cooler when both cards are overclocked. The use of a single heat pipe is most likely the culprit when comparing the Sapphire and PowerColor cooling solutions.
