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).
Noise levels look pretty strong, sitting below the half way mark as you'd hope. The idle number, though, is particularly strong, coming in a little over 50dB. Looking above, you can see that's considerably lower than a lot of the other cards that sit around it.
