I'm thinking of setting up a multi-GPU cluster for running

cant even run crysis on medium settings

Those 40mm fans in those server cases blow a shit ton of air and sound like jet engines because of that. They are usually enough to cool GPUs and such. Even nvidia's dual GPU tesla has a passive heatsink and some cutouts on the side so that the case fans can bloe directly to the heatsink.

using open air coolers packed that close together is asking for a housefire. get some passive coolers and make sure the case has good fans instead.

literally why

Do not use a case. Crypto-currency miners do this all the time.

You can either use a wire metal shelf or buy an open air frame on eBay. People have been doing this for years. Whatever you do make sure it's conductive and that the PSU is mounted to the unit itself so things are grounded properly.

Put a box fan behind it, and you'll have better cooling than any case would provide.

that's great if space isn't an issue, but if you're not on a budget a rack and a bunch of 2u cases can pack a lot more GPUs.

You can't use water cooling if the cards don't leave enough space between them for the pipes.

There are server cases with PCI-e risers that gives you enough breathing room for 6 or 8 GPUs. You can get those for about 400-500 bucks.

A cheaper option is to use threaded rods to stack components up at different heights.

Maybe you mean running CUDA programs.


Get a life cracker...
