We have changed our method of measuring noise levels. 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 system. It also brings us slightly closer to industry standards, such as DIN 45635.

The Alienware X51 isn't the quietest system we have tested. That said, when watching a high definition movie file, it hovered between 33.3 dBa and 34.8 dBa.
You can certainly hear that it is on most of the time, however when idling the fans drop to almost inaudible levels.
When tasked with Prime and Furmark, the fans spin up fast to compensate for rising temperatures.
We wouldn't say this system would be ideal to be left on 24/7 in a bedroom environment. For a living room however it is ideal.
Thats really very sexy looking. I like it. Wonder if you can fit a better GPU in it. would the PSU handle it?
Nice photos. I was going to say I wonder why they hadn’t moved to the new 3rd generation processors, but I notice they just did. good move 🙂
Its a nice idea, but the power brick is massive. kinda ruins the point of having such a small case. no?
