The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 23c – a comfortable environment for the majority of people reading this.Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.
Idle temperatures are improved over the reference card by 11c, under load.
The GPU is using Nvidia’s GPU Boost 2.0 which dynamically adjusts clock speed and voltage settings, factoring in temperatures.
We install the graphics card into our system and measure temperatures on the back of the PCB with our Fluke Visual IR Thermometer/Infrared Thermal Camera. This is a real world running environment.
Details shown below.
EVGA have added a backplate to this card and temperatures on the rear of the PCB are much more evenly distributed than the reference board. The hottest part is the reverse side of the GPU core area. We managed to increase temperatures to 73.5c in this area after 30 minutes of Furmark. This is strictly a worst case scenario. This is around 10c lower than the Nvidia reference card and will help improve the life span of the hardware.
