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.

The Asus GTX780Ti ROG Matrix is clearly audible under load, but the fan noise isn't that intrusive due to the pitch of the fans.
Why always the talk of 6gb cards? Every benchmark I read suggests it doesn’t help a Titan Black leverage again a 780 Ti. I play games in 4k with two 780 Ti’s in sli and never see my vram usage hit 100%. The issue vs AMD cards is the 384 vs 512 bit bus. A Titan Black is simply wasteful for gaming purposes.
I am looking to get another 780ti for sli 2 way.. I game in 1440p Surround.. Will I be able to obtain 60fps on very high settings?
7680x1440p is very demanding; SLI 980Tis is what I use, but I use my 780Tis for 2650x1440p. I think if the 780Tis had 6GB of VRAM instead of 3GB they would do ok @7680×1440.
So true, I have my Asus Rog Matrix 780ti on ebay as we speak, I will miss it for sure though, decided to go for 980ti’s – for the ports at the back too.
