Ambient noise in the room is around 20-25dBa. We measure from a distance of around 1 meter from the closed chassis and 4 foot from the ground to mirror a real world situation.
Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on only the video card. It also brings us slightly closer to industry standards, such as DIN 45635.

The Armari is only slightly more noisy under load than it is when idle. In both cases, it's incredibly quiet, scarcely audible above the background level. This won't be a system that will be at all irritating to work alongside.
Looking at this URL http://www.armari.co.uk/custom.asp?SysID=695 , for the “M16-AW1200R-GPU”, I could not see how you came up with a price of £5508.75. Do you have a URL for the System you tested ?
PS: They have a 8-GPU System @ http://www.armari.co.uk/system.asp?SysID=1405 , the “Tyan FT72”.
Thanks for the detailed Review.
