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. Note that the temperature values are reported as deltas rather than absolute temperatures with the delta value reported calculated as GPU temperature – ambient temperature. 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. Water-based Testing Configuration and Benchmarks Used.WATERCOOL HeatKiller GPU-X3 Core Layout and Design.We take some tools to our new and shiny EVGA GTX 970 SC ACX 2.0 card in a quest for better temperatures and higher performance….Introduction and Technical Specifications.We managed to increase the GPU clock by 90MHz, while the memory clock easily went up by 200MHz (effectively 800MHz). You can learn more about it here, in EVGA’s Precision X FAQ. The software even supports non-EVGA cards and we suggest you give it a try, since it tends to offer a bit more than classic overclocking tools. Multi-language support: English, Dutch, French, Traditional Chinese, Japanese, Korean, Polish, Russian, Spanish, Portuguese Support for wireless Bluetooth overclocking via custom Android app Custom skins including ones created by the EVGA community! In game screenshot hotkey, supports BMP, PNG and JPG formats Robust monitoring allowing ingame, system tray and/or Logitech LCD monitoring Profiling system allowing up to 10 profiles with hotkey GPU Voltage Adjustment + Overvoltage (GeForce GTX Titan) Pixel Clock Overclocking – OC your refresh rate! Temperature Target Control (GeForce GTX Titan) Power Target Control (GeForce GTX Titan / 600) EVGA has a habit of rolling out new versions of its popular overclocking tool along with its new graphics cards, allowing consumers to get full support from launch day.
