I don't understand why so few people separates the cards as far as they can and why nobody change card orientation so fans don't get blocked by other cards.

Because I was in a hurry to get mining and now that i'm overclocked and mining 24/7 my temps are fine so, why bother with it? |

what are the temperatures on the 2x 6990?
The lower card GPUs are at 64/61 deg and upper are at 76/69 deg. They are running with the OC switch in the default (non-OC) position to reduce power consumption. With OC enabled one of the upper card GPUs likes to get up to about 90 deg, and the rig draws nearly 2 more amps (~7amps vs ~9amps). Right now I am using the Koolance Exos 2 all in one cooling system. Very easy to setup and nice design. However, the Exos 2.5 (with 3 fans instead of 2) is probably better suited to dual 6990's - got one on order to see what kind of difference it makes. |

my 5830's, hard at work  ::sniff:: i am so proud of them... card temps between 57C and 63C aluminum frame cost about $12. the coffee cans were a temporary solution, although i think all i will do is turn them upside down and drive some self-drilling screws through the frame into their bottoms to make them permanent. i run this rig via Putty SSH on a WinXP rig in the other room. this whole deal costed me a little over $750 (counting the box fan) and gets 1040 Mhash/sec  |

Any insight into your water cooling setup for those of us that have never done it before? I understand the concepts, etc. but I have had a hard time getting my hands around the options available on the market for 1000W+ heat dissipation. |

Build yesterday Hmm very nice idea... does it work well to isolate the card that way? I imagine so since it would create a windtunnel-like effect but it would be nice to make sure. |

From my preliminary tests it seem to work very well with a 5850 @ 1000/900 1,21 Vcore and 60-70% fan i was able to keep it around 71 degrees too bad the VRMs are more or less cooking (135 degrees), i checked all the screws on the back of the board today tough and one of them was a bit loose so that might have been the problem with the VRMs, i'll check later |

what are you guys using for "open" cases with 4 cards?
Spreading the cards out as much as possible and strapping a fan to the top of them. That does the job. What I meant was which test benches or cases or whatever are being used? |

I have two rigs mining but this is my main one:    Two 5870's. One is overclocked at 1120/500 → 469 MHash/s. The other has a minimal overclock (900/600) → 376 MHash/s. |

what temp do they run at? Running mine at 950/386 at around 420Mhash/sec and don't have any temp problems with just air cooling. Will |

[/cheap irony]
Hahah! I normally leave the UV cathode off. Had it on for looks.  what temp do they run at? Running mine at 950/386 at around 420Mhash/sec and don't have any temp problems with just air cooling.
Will
The one mining 469 MHash/s is averaging 38°C. The other is at 34°C. |
