Multi GPU Renderer

[T_Girrap]

Hi All,

 

I'm trying to get an idea together for a 3 gpu system for GPU rendering using redshift/octane.  I work at a small design company in Australia and the ultimate plan is to have 2 or 3 of these setup in a rack in our office with a render manager to split the work across them.

 

My proposed config is

 

MSI X399 Motherboard

1900X Threadripper

Silverstone 4ru Rackmountable case

Corsair 1200W PSU

3 x 1080ti Founders edition

32GB DDR4 Ram

1TB SSD

 

My main concern is with cooling.  Does anyone have any experience with running 3 gpu's in a case like this?  I'd really like to avoid water cooling if possible, additionally as they will be rack mounted with other equipment loud fan noise isn't too much of a concern.

 

If anyone has any thoughts on this setup and could advise on the cooling required I would be very grateful!

I would think perhaps using 3 Radeon 7 GPUs would be better or 2080 judging by current pricing. 

 

Also why only 3?

 

Use splitters to run them in 8x or 4x and run even more in a single system. In most workloads you wont be affected.

 

 

Edit: i can tell there is space restrictions. But its food for thought

Thanks for the quick response,

 

Unfortunately both Octane and Redshift require Nvidia cards currently so I'm locked into Nvidia for the time being.  Additionally we actually have quite a few 1080ti's available at the moment, so while I appreciate there are better cards available for the price, its the only part of the build where we have the parts available free!

 

It's a good point regarding using more than 3 cards, my main thinking behind it is cooling and keeping the form factor rackmountable. Also, I've seen issues with stability with some systems when loads of GPU's have been crammed in and I'm really keen to keep it as painless as possible

I would like to consider a better GPU except a founder edition cards replaced with triple fan design or dual fan design and if possible use some good branded fan's of corsair or coolermaster 140mm and 120mm for cool air intake and hot air out , make this case management like this.So, That every part is getting enough air flow.......
