For all tests, room ambient temperature was maintained between 24-26C. Note that the temperature values are reported as deltas rather than absolute temperatures with the delta value reported calculated as GPU temperature – ambient temperature. During the tests with the modified card, it ws found that a minimal amount of airflow was needed blowing across the VRM heat sinks to prevent card instabilities. To adequately measure the EVGA GTX 970 SC's cooler performance, performance testing was done for all scenarios under two operational conditions – air cooled using the ACX 2.0 cooler, and liquid cooled using the modified configuration with the HeatKiller GPU-X 3 GPU water block.

For both the idle and load temperatures, the highest recorded value in the application were used for the run. Temperature measurements were taken directly from the GPU thermistors using TechPowerUp GPU-Z v0.8.2. This procedure was repeated a total of 12 times – six times for the stock speed runs and six times for the overclocked speed runs. After each run, the system was shut down and allowed to rest for 30 minutes to cool down. To replicate a stress graphics load, EVGA OC Scanner X was run over a 30 minute period using the Furry E (GPU memory burner::3072MB) 3D Test, a 1280×1024 resolution, and an 8x MSAA Antialiasing setting. To replicate GPU idle conditions, the system was rebooted and allowed to sit idle for 30 minutes. To best gage the quality of the GPU cooler under review, GPU temperature was taken with the graphics card idle and under load.
