Quote from: Ryu.Hayabusa on July 21, 2011, 07:32:42 AM Running cooler than my single 5870, so that's definitely a plus. Good PSUs have short circuit protection, so if a trace were to arc over to another and start smoldering, either on the GPUs or the Mobo, the PSU should kick off and will continue to until the short is gone. What make/model are the PSUs you're using? Raidmax 1000w http://www.newegg.com/Product/Product.aspx?Item=N82E16817152044&Tpk=raidmax%201000 Each system draws just under 700w under full load.

I have a fan blowing over everything already. I just logged in to the server and all of the cards are currently running at 74c.

Quote from: bmgjet on July 21, 2011, 03:39:30 AM Id be worried about fire's as well. Such as a rat gets up there chews cables shorts it out computer goes off rat dies. Youv set it up to turn back on so it does, brings rat back to life and lights it on fire. Flaming rat runs around spreading fire. You all are starting to freak me out about the whole fire thing...

If it got too hot, I would assume that it would simply shut off. I also used a very heavy gage extension cord for that reason. 3) Thanks! 4) I was actually thinking of doing that. I was going to screw some wire into the plywood that the computers are mounted to and attempt to suspend it from the rafters above the drop ceiling. Although it's harder than you might expect to accomplish all of this with the small amount of access space I have.

This is the 1x connector that I am using. http://cgi.ebay.com/PCI-Express-Card-Extension-Cable-PCI-E-1X-Riser-Bitcoin-/260820187941?pt=LH_DefaultDomain_0&hash=item3cba183b25

I have the connector on all 8 of the cards. It is just a regular DVI to VGA adapter with resistors in them. Why? Well they are there to trick the computer into thinking that a monitor is plugged in. Otherwise the cards don't show up in windows. I use Logmein Free to remote into the computers to start / stop the servers. They are set to turn on on power failure, so I can always restart them by unplugging them from the wall and plugging them back in.

The temperature is not bad. The hottest I have seen the GPUs get up to is 84c. There is no noise what-so-ever. I ran the power through the ceiling and plugged it into a storage closet across the building. The only problem that I am having right now is that one of the cards seems to have gone out and I can't fix it without taking it down. Also, the ceiling looks like it might cave in at some point. I'm having a difficult time finding opportunities to work on this thing without anyone noticing.
