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).
It's also awesome to see that those low temperature number aren't coming at the cost of high noise levels. The card is near silent when running.
Maxwell and the Twin Frozr IV combination is a clear winner.
