Pulling out the TES 1350A Sound Level Meter we find ourselves quickly yelling into the top of it to see how loud we can be.
After five minutes of that we get a bit more serious and place the device two CM away from the fan on the card to find the maximum noise level of the card when idle (2D mode) and in load (3D mode).
The noise levels are just insanely low, considering the power of the setup and the temperature the cores are running at under load, these numbers are just so low.
They were so low that I found myself triple and quadruple checking that the numbers were correct. This is a real testament to not just the quality of the dual fan cooler, but also the 28nm AMD GPUs.
