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 on the GHz Edition of the HD 7970 are pretty similar; you can see the reference cooled Diamond card come in at 59.3dB / 62.9dB while this card comes in at 60.8dB / 63.5dB.
So while we've got a couple of extra degrees present on the new GHz Edition card, we can see that we have no real change in noise levels.
