XFX R9 290X Double Dissipation 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.

- 5-run sequence
- 20-minute idle duration
- Temperatures measured in degrees Celsius
The value of an improved cooling solution is evident in the thermal results. Running the stock clock speeds at both idle and under load, XFX's Double Dissipation cooling solution delivers improvement over the reference cooler. At idle, there is a 14.5% improvement and under load I see an almost 18% improvement in thermal performance. That equates to a 6 °C reduction at idle and 16 °C reduction under load when compared to a reference-cooled card, like the comparison R9 290X.
Overclocking shows that when the fan speed is maxed out, the reference cooler is actually the better performer based purely on the thermals. That's a good thing, but when you add the noise generated to the equation, while the XFX R9 290X is 10 °C warmer, it's in another league altogether. By comparison, the Double Dissipation equipped card is quiet. Even when the fans are maxed out, the XFX R9 290X is, by definition, a quiet card.
