You get used to the fan "noise"
I don't want to hear that noise because I'm living with this thing computer over here 
I'd rather run them hotter because I will sell them anyway when asics comes..

There was my config file. Mems are 180 / 190 / 180
Yep I see it now. But you still don't have any fan control set up in CGMiner. "--auto-fan --gpu-fan 25-75 --temp-target 70" will do you wonders.

Those are really hot. You sure the mem is properly set to 300? What are your fan settings?
Here is how I'm running these now.
And here is the output :
Cards are
GPU 0 = Asus Reference 5870
GPU 1 = Asus EAH5870 (I use it also for main display and for gaming)
GPU 2 = Club Reference 5870
The best clocking one is EAH by all means and what comes as not a surprise the club one clocks the worst.

I'm actually struggling installing/downgrading to sdk 2.1 and 11.12 from 12.8 and sdk 2.7 under W7 x64. CGMiner 2.7.5 didn't like the sdk 2.1 and said that no devices was found/usable even though 2 lines before it lists the sdk.
For some reason, standalone 2.1 SDK doesn't have certain things present to allow miner software to detect it. You need another SDK installed along side it (2.4 or higher). Use the "gpu-platform" command to select the appropriate 2.1 sdk platform once you have both sdk installed

I had some similar problems but after I cleaned my comp out of all ATI-drivers I managed to get it working
-fankih-
try grabbing cgminer 2.5.0 and see what happens. The newer miners work better with the new hardware 79xx series. Older miners are better with older software.
Where did you read that? I've never heard of that, and I've always used the newest CGMiner. Actually the newer miners should run more efficient, and actually give better results.

5830 = 950c/300m/1.05v = 315mhs
5850 = 925c/300m/1.05v = 385mhs
5970 = 805c/300m/1.05v = 375mhs/core 750 total
6870 = 950c/850m/1.162v = 297mhs newer sdk and driver-2.4, 12.1 i think that is what this one is set at
I put 2.1 SDK and 12.1 drivers and got those running 1200MH/s with 855/875/850 clocks and 1v on every card.
855 ~392
875 ~400+
850 ~388
But yes I'm going to sell all of them when ASIC's comes out.
Can you tell me how exactly you downgraded to 12.1/2.1? Did you do some tricks or something? 855 ~392

The memory I'm running those atm is 180MHz. Would it actually change anything to drop down those few MHz more?
Very minor saving in power and heat, nothing more?

So if I understand correctly, the SDK 2.1 gives best performance for a 5870, but what about the driver version?
Those are very low hashrates for those clock speed.
Install 2.1 SDK, verify the 2.1 SDK is installed, and make sure to select the platform when booting up cgminer with the "gpu-platform" command (first platform is 0. 2.1 will likely be platform 1). Also use phatk kernel, worksize 128, and vectors 2. Lastly, you said engine clocks are 865, 840, 860. Use these memory speeds in respective order. 173, 168, 172. You should get 401, 389, and 399 mhash respectively.

Quite simply I brute forced every reasonable memory frequency for every multiple of 5 core frequency between 675 to 1050. I plugged in the best hashrates and memory speed per core speed into my handy dandy TI-82 and got equations, and voila.
I put 2.1 SDK and 12.1 drivers and got those running 1200MH/s with 855/875/850 clocks and 1v on every card.

1050 is fine.
It's not fine, tho. He should be >1200Mh/s. 
1050 is fine. Just get ready to sell them on ebay. None of this will matter in 6 months provided BFL delivers.
SDK 2.1 will do better for 58xx series. 5830,5850,5870 Got 5 x 5830 pushing almost 1.6 gig, 5 x 5850 almost 2.0 gig and 3 x 5970 little over 2.3 gig.
The odd mem speeds are a ratio based on core and mem speed (i believe). driver 11.10 is the one i use, i think.
