Sound Test

 

 

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 while almost identical to the single card setup are still very much on the loud end when you overclock so high.

 

Of course if you're going to use the card at the default speeds you're not going to have a setup as loud. But if you want to crank up those clock speeds and increase the voltage that does come at the cost of extra noise and temperature.
