Sapphire Radeon HD 5870 2GB Vapor-X Video Card

Sound Tests

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 card are fantastic. Looking closely, you can see it's the quietest idle card we've tested to date. The Vapor-X has always done a good job and on the 2GB HD 5870 there's no difference.
