ASUS R9 280X DirectCU II TOP & R9 270 DirectCU II OC Testing:

Temperature testing will be accomplished by loading the video card to 100% using Unigine Heaven Benchmark Version 4.0, with MSI 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 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 twenty-minute cooldown, 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

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

At stock speeds, the ASUS DirectCU II equipped R9 280X easily kept pace with the Tri-X cooled R9 280X Toxic at both idle and under load, showing off the strengths of ASUS' design. The R9 270 fits right within that cooling envelope by comparison. Neither of the three offer the lowest idle temperatures, but show how effective they are under load.

Overvolting the core drives up heat even higher. ASUS plans for this eventuality, as many gamers will look for that last FPS as the card ages, by building a cooling solution that can take the increased thermal dump added voltage and core clock speed bring to the table. The ASUS DirectCU II equipped R9 280X TOP actually cools slightly better in my tests by a single degree over time. Pretty impressive when you look at how well the Sapphire card does in this metric.
