Added another 200Khash in overclocking ;D and with only a few degrees heat increase. See post above for new stats.

Thats some cool numbers.As a hint when doing ducting with fans: You can make it worse with ducts. I suggest using cardboard or similar material that you can fast move and alter for first trials while keeping your temperatures in constant view. If you do it wrong, you might actually deflect your fans power from where it needs to be.

Thank You Christian.
Excellent, I have corrugated plastic board which is similar to cardboard but stronger.
I can use that for testing.
Once I get the size and shape correct, I can make a metal duct. -

Be careful with the plastic, it might melt… Cardboard can catch fire, but usually takes a bit more than the plastic melting point :)A good begin is to get directly form the fan to where the cards start. Close holes on the sides, etc, then the air should get much more direct on target.

Still cant help but think you’re over thinking the cooling/ducting. I have 3x 12" desk fans that cool all 5 of my rigs. Current temps on Miner-01 65,63,66,70. KISS (Keep It Simple Sir).
Oh and if you manage to set fire to cardboard on your GPU’s - you’re doing something very wrong. :P

Rig stats updated :P Please let me know if you think I’ve missed something.

Top Man!
The Sapphire stats aren’t mine though. :-\

[/quote]Woops haha let me fix that
-
Two cards were replaced.
-
I have 3 x 7950’s temps are abit weird.
Temps are - 59, 69 and 89
Seems which ever one i use in slot one cant keep it under 89? I have to run this @ only 460 k/hash while other are on 600 k/hash with no problems.

Slot 1 being the slot closest to the CPU or the one balancing on the soup (one way to warm your lunch!).
If it’s the CPU side (though the pictures imply that you are calling the soup card slot 1) then that’s normal for the gigabyte windforce as the fans suck in the hot air from the back of the card in front - great cards but awful cooling design!
If you mean the “soup card” and your sure all 3 behave the same then there is a serious issue there. Are you using afterburner or something like that to OC? Maybe it’s screwing with your fan speeds and preventing them from spinning up? What does CGMiner say about the fan speeds?
-
Lol ran out of beans ;)
The one cloest to cpu is the problem thinking of using a riser cable on it to see if makes a difference getting it away. As there are 2 cards close togther and if they suck air rather than blow could be the problem?
Use afterburner only thing changed is fan speed 100% all other settings are stock as unsure of oc settings. If i leave on autofan speed computer is i in ide state in morning and team viwer unable to connect and have to reset.
No sure about cgminer use gpuminer with intencity @ 18 on 2 cards getting 600k/ hash and 14 on high temp geting around 460 ish. Shame can get that third one bit faster
-
On the back of the 2 cards on the mb where you have the card outputs i have a pc fan blowing into there should i have that the other way around if the fans on the card are pushing the hot air into the colder air coming out of the fan?
-
2x5850’s using cgminer with the standard scrypt config. Nothing special. Both cards OC’d a little. Getting around 650Kh/s combined but I am solo mining.
-
How are you getting on with solo mining? I had all mine going for a day or 2 before the inrease in difficulty but didnt hit any blocks :(
-
tbh you’re gonna struggle with those cards plugged directly in to the mobo. The air gets diffused all over the place rather than neatly out of the backplate (connector end) which is fine for a single GPU but useless for multicard setups. Raising the card so i can suck in cool air rather than the hot air from the back of the card in front (clue: shut down the rig and feel how hot the back of the card is) will help hugely. I tried the 120mm fan trick but ended up with a bunch of 12" desk fans.
Go to page 4 of this thread for some pics… Pyxis uses 4x 7950’s and i use 4x 7970’s and we both came up with the same(ish) designs although Pyxis looks more refined ;).

Thanks for the help, will check it out and see what i can do.

[/quote]Jeese Nut, just seen your rigs, what is the total combined wattage of all that? Gotta be touching 6000/7000W+ what are you plugged into? The Cooker or Shower ring main? :D
-
Just shy of 7000w including the fans and the AC unit which runs on fan only mode most of the time (anothe 1.5kw when it gets too hot).
All running from the neighbours shed! :-X
-
Several machines running multiple or single cards at PC repair shop in Burbank.
7950 -550k
7850 -345k
6870 -365k
7770 -120k
5770 -140kSome of the systems are being used for data recovery too offset Cost of mining.
My PC repair shop is located at 340 N victory blvd. Burbank CA 91502. 8184506705 if you need a quick help with mining hardware.
