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 system is quiet when idle and the fan speeds rise under load. Even under load it is reasonable, audible but not distracting.
Well I love PCSPECIALIST too, but this is better than anything ive seen from them this year. have they a new system builder team in there? my mate has an OCUK from 2 years ago and its a POS.
Well im not a fan of prebuilts either, but this is as good as I could build myself. better if I was being honest. shame they dont offer the 4770k, id like the four extra cores
I still think you could spec a system like this for a few hundred less. still, nice build.
Haven’t ordered from OCUK in years. just built my own system. Have to chip in with a vote of ‘good build’ too.
I noticed the motherboard immediately, gettign sick seeing asus boards recently on kitguru, so nice move from OCUK.
That corsair case is great, my friend bought from scan a while ago, its tiny, cant tell that from the pictures. very portable and light, but well built.
They make great products, good to see the PSU, cooler, case etc, are all corsair. Is the PSU ok? never seen that model before.
Still prefer the 3570k or 3770k, they could have got it to 4.8ghz easy with that cooler. No need for integrated graphics with a GTX770.
Intel are sucking this generation.
