NVIDIA GeForce GTX 980 Ti 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 1920 x 1080 using 8x AA 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 1920 x 1080 8x AA
  • 5-run sequence
  • 20-minute idle duration
  • Temperature measured in degrees Celsius

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 
 

 

The cooling capacity of NVIDIA's reference cooler is more than enough to keep the GTX 980 Ti out of thermal trouble in both stock and overclocked scenarios. The results from the GTX 980 Ti most closely match the other GM200-based card, the GTX Titan X, both at stock and overclocked settings. Debuted when NVIDIA rolled out the Kepler-based GTX 690, the industrial looking cooling package has proven to be both a quiet and effective solution over several GPU generations. You can get cooling performance out of many heat sink packages as long as you turn the fan speeds up to move more air through the card, but doing so creates a pretty severe noise penalty.

While running at stock speeds, the fan on the GTX 980 Ti, much like the vast majority of NVIDIA's most recent cards, is very quiet under load. Spool up the squirrel cage to 100% and yes, you will hear the GTX 980 Ti, but the nosie is nowhere near as severe as some of the reference cooling solutions out there. With more hardware under the hood you will see slightly higher temps from the GTX 980 Ti as it compares to the GTX 980. I saw a 3 °C rise over the GTX 980 under load at stock speeds, but when you put the screws to the cards and ramp up the fan speeds, the GTX 980 Ti was two degrees cooler.
