We have built a system inside a Lian Li chassis with no case fans and have used a fanless cooler on our CPU. The motherboard is also passively cooled. This gives us a build with almost completely passive cooling and it means we can measure noise of just the graphics card inside the system when we run looped 3dMark tests.
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. Ambient noise in the room measures close to the limits of our sound meter at 28dBa. It isn’t a real world situation to be measuring with a case panel off only a few centimeters away from a video card.
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.

Generally, the system is quiet. However this is far from the overall picture.
When the CPU is under heavy load situations, the fans spin up quickly to counter the rising temperatures. When both R9 290X and i7 4770k are stressed all of the fans spin at very high speeds. The system at full pelt is very noisy and the first time this happened I thought the case might actually take off.
Generally however when gaming we recorded noise levels around 37-38dBa. Acceptable, if a little higher than we would like.
Adding in a Corsair H60 might help to reduce noise levels a little as the MSI CPU cooler fan does spin very quickly when the temperatures rise.
I think its quite attractive, although the handle at the front puts the whole shape out of sync or something.
They are taking quite a stance with the high end stuff inside, surprised it didnt just turn off under load 🙂
Yeah I love that, but I would want something a little more cost effective as a build, must be about £2k of hardware there in that. If the barebones is around £300, I would say £1k would get a great system. Something like a GTX770 and a 4670 would work for me.
