AMD R9 Nano Optimized; Temprature and Clock Speed Results
Undoubtedly, the AMD R9 Nano is as small as high-end graphics cards come, and on top of that it is pretty powerful. However, when you are asking high performance, temperatures become an issue, which is why it is important to note how much of the performance can be improved by optimizations targeted at temperatures.
The results below are from an optimization test held by PC Games Hardware using Undervolting, a full cover waterblock as well as high performance thermal techniques.
During the test, AMD R9 Nano was optimized with air and kryographics watercooler at different settings. At standard clock speeds the voltage was reduced by 60 millivolts. One effect this had was to reduce the sounds.
Then the card was accelerated by 30 percent of the target power; instead of 175 watts it was given 228 watts. With the test they were able to overclock the card to 1050 MHz.
With 2250-2400 rpm air cooler speeds, GPU temperatures as high as 75 degrees Celsius were recorded while VRM temperatures went up to 84 degrees Celsius. However, after the cooling solutions were applied, the GPU temperatures went up to only a maximum of 43 degrees and the VRM went up to only 30 degrees with normal power targets.
Even at highest power targets, the temperatures didn’t go beyond 65 degrees.
The tests were carried out using four different games namely Crysis 3, Far Cry 4, Rise of the Tomb Raider, and The Vanishing of Ethan Carter Redux. Here are the performance results for each of the game as recorded.

The Vanishing of Ethan Carter Redux
Last but not the least, the AMD R9 Nano optimization tests have also revealed that the water cooling changes only have a small effect on the performance in terms of FPS.
Here’s a breakdown of the frame rates per second changes that were observed with each game at different settings:
