Quiet and Powerfull rendering computer


I'm using since 5 years a Barton 3200+ downclocked to a 2500+ for a permanent heat problem related to a bad motherboard, a Asus A7N8X-E Deluxe (reboot at 60 celsius...) and a XFX 7800 GT.

I mostly use my computer to render image with POV, blender and cinema 4D, play some FPS (800*600 low quality... Fallout 3 is a bit different...) and watching some videos.

The computer is really noisy and stand at 2 meters from my bed... not really cool for a "all night" rendering session...

I'm bored, really bored now, I calculate than the CPU is at less 15 times less powerfull than a i7 920, and i don't talk of the gaming system, and the permanent noise...

Now I almost manage to keep enough money (I really don't like credit...) to change all and take a new step.

So please can you help me ?

- Ultra quiet
- Allways On
- Rendering computer
- No overclocking

- 5 years computer duration
- No vibration
- Tri-CrossFire capability

- Lowest numbers of different shops

- Want to place order late february

Don't mind:
- Not a storage computer

More about quiet powerfull rendering computer
  1. I don't understand everything you said here, but I suspect you are aiming a bit high... in other words you are spending more money than you need to spend.

    You can do everything you need to do with a Q9550, an x38 motherboard, and two quiet 4870 1GB GPUs.

    If your English reading is up to it:
  2. Hi Proximon, thanks for your answer.

    Sorry to be hard to understand... to sum up, I need a powerfull and really quiet rendering computer capable of some fps and that will be used during 5 years and that is not a storage computer (big disks and DVD drive are useless).

    Why I select a i7 core over a Q serie processor ?

    because it's really fastest for the need I have.

    For the noise, I want something really really quiet even if it cost, my PC is in the same room where I sleep and I'm bored of the "low noise" that is claims everywhere, 45db is inacceptable for me and mine is over 50db, 25db is my dream.

    Spending some hours and changing a few parts, abandon some others, I found 2 shop that can provide all, LDLC and Caseking, both europeans, for around 2150€.

    I think my choice are the good one to build a really quiet and powerfull computer but I still have 2 big questions :

    Did I have enough power to do a tri-crossfire with Gigabyte GV-R485MC-1GH and use it ?
    Will it be as quiet as I imagine ?
  3. Will it be as quiet as you imagine? I doubt that.

    Understood on the whole rendering thing. You need as much CPU as you can afford. OK.

    You are spending a lot of money trying to make air cooling as quiet as possible. You seem to have a good understanding generally of what that takes.

    Maybe your money would be better spent on water cooling?

    A very high quality 850W would probably power 3 4850s... but I'm not convinced the Zalman is that unit. No one with proper equipment has reviewed one yet... Anandtech came close but seems to have gotten some bad and inconclusive results.

    The harder you push a PSU the louder it will get. A Corsair 1000HX might be a better choice.

    I think you'll get better results with a good custom water cooling build. If that interests you, the link I provided in my first post has a link to some water cooling information. Ask in our cooling forums for any specifics.
