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.
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.

When idle, the Asus GTX760 MARS is basically inaudible. When loaded however, the fans quickly spin up, and it is clearly audible, although not close to the same level as the reference cooled AMD R9 290/X. The fans spin between 1,200 rpm when idle and 2,800 rpm fully loaded in Furmark.
This is very impressive. always liked the GTX760 for the power to performance ratio. nice job.
Very interesting, I always thought MARS cards were priced intentionally well outside the realms of normal solutions, but ASUS are making this one practical as well.
Its a good idea, but it should maybe have a different name, not MARS.
Very nice idea, I see a lot of people complaining that it is no longer a ‘MARS’ card, but they weren’t practical at all for anyone, over the top pricing etc. Maybe asus want this one to sell well, and it should actually as its a decent saving over the 780 TI, and closely matched.
Why there is no comparison of gtx690, amd7990, or some SLI/crossfire?
The Chart is not complete without these comparison….
