Testing:

Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 2.5 with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1200 using 8xAA. I will use a 5-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 be a 20-minute cooldown with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running the overclocked idle and load testing.

Settings

  • Monitoring with MSI Afterburner
  • Unigine Heaven 2.5 1920x1200 8x AA

Lower = Better

The temperatures delivered by the Sapphire HD 7970 show that the work AMD did on the fan and opening up the opening on the mounting bracket pay dividends when compared to the last gen HD 6970. There was an 8 degree delta between the two cards. When overclocked the the delta between the Sapphire HD 7970 and the HD 6970 remains a constant.
