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 great. Under load the card hits 84c after a short while. 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 on each test are shown below.
Above, a traditional heatmap analysis. Without a backplate on the PCB the card does get quite hot to the touch. A large portion of the PCB heats up to around 80c, with ‘hotspots’ hitting almost 90c.
The above heatmap is using an alternative high contrast overlay to better show the hotspots. You can see several positions clearly – peaking around 90c.
