Powercolor Devil R9 270X 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 1920x1080 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 cooldown, 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
















When I look at the temperatures delivered by the Devil R9 270X it delivers warmer temperatures under load than the Twin Frozr equipped R9 270X. This result was not really expected based on the cooling solutions used by both manufacturers. At stock speeds the Devil R9 270X is out cooled by the Devil HD 7870 that uses the same cooling solution. Yet when overclocked the latest revision of the silicon runs a bit cooler thanks to the lack of voltage control. Overall it is one of the cooler running cards in the comparison field. Using three fans you might think this fan is going to be incredibly loud. Quite the contrary. You are presented with some noise at 100% fan speeds, that's a given but the noise is easily muted when packaged up inside a chassis. The rattle I observed on the HD 7870 version of this card was not an issue with this sample.
