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).
At 65.6dB, Quiet mode isn't exactly all that quiet. Saying that, though, this isn't a terrible number at all and we see it's up there with many other high-end single and dual GPU video card offerings.
Turning to Uber Mode, though, that does bring a noticeable increase in load levels. We end up hearing as high as 75.9dB, and if you're in a quiet room, play with your speakers low, or have a poorly insulated PC case, this is a high number.
