My basic understanding of overclocking and computers is being tested here.. so I thought I would reach out for some help on this topic.. The problem reads as follows.. I have 2 gtx 570 stock cards in sli. Now I go into MSI after burner to do a mild overclock and run a stress test to check temperatures and over all stability.. they will stay stable.. but the heat gets out of hand and keeps on rising.. now I won't accept anything over lets say 90 degrees Celsius because I think that's 2 hawt I have noticed that the bottom card seems to bleed heat into the top card and cause it to run about 5 degree's hotter then the card below it.
I can run the fans at nearly max and the feed back loop of heat seems to continue unabated. Anyone know any tricks or reasons how this is happening or how to fix it?
GTX 570x2
Voltage 1061
Core clock 850
Shader clock 1700
memory clock 2000
I have a haf 922 coolermaster case with the fans running at max
Like I said I can run the fans on the gtx 570's at nearly max and the heat loops continues
I don't have anything obstructing air flow and the case is sitting on a hard surface on my computer desk.
STABLE OVERCLOCKS:
semlethe3rd - 950/2050 1.088v water
b0sse 950/2000 1.1v water
maledragger - 924/2000 1.063

Chris Ihao - 850/2000 1.063v
CloudCR - 810/1980
kerkk - 800/1975 1.013v
Here are some over clocks people are claiming to have done.. I kinda cheated and use these as a baseline for what im trying to accomplish.
I have all ready over clocked my i5 processor and got it nice and stable.. so figuring this out would be awesome!
Thanks in advance for your help!

Well this is pretty normal for SLI 570's.
You didn't even mention what models you have.
If you don't already have one, a side 200mm intake and/or bottom 140mm intake will help a ton. |

| OP might have fan cards instead of blower cards. Blower cards are better at dissipating heat when stuck next to another device. Also because heat is discharged out the back of the computer case instead of into the computer case. |

I have 3-way SLI 560 TI 448 and I overclock to 1000 core clock, 1760 shader and 2100 memory, fan speed around 44%
As far as I know, 570 and 560 TI 488 are VERY similar, so you should achieve the same as I got, as I think this is the the absolute maximum you can do. Whats the cooling like for your SLI? I have 200mm intake + bottom and as Wabbit said, it helps a lot. Average temps after 6 hours of Battlefield 3 on maximum settings is 66-77 degrees celcius alpha. Last edit: 2012-07-24 07:42:16 |

Temperatures should peak after a few minutes, or come very close to it, whereas alt tabbing for 10 seconds to check temps could drop them like 20c |

I don't understand. Temps are written on your screen with Afterburner. |

Many people use methods for checking temperatures which involve alt tabbing, and taking load off cpu/gpu which drops temperatures a ton very fast |

But 60-80 to 20 in a second or two? |

Well, assuming you're using HWmonitor, alt-tab isn't an issue anyways since it records max temps. Anyways, how to measure temps seems pretty secondary to how to keep cool. Edit: At least to this OP.
OP: how many empty slots are between the GPUs? And, of course, as was mentioned, model is really important.
Actually, IIRC, afterburner has graphs, like Precision does. I know Afterburner does logging if you enable it. And that's assuming you're not using OSD for some bizarre reason.Last edit: 2012-07-24 09:03:14 |

I meant drop by 20c, Like from 80c to 60c or lower, people seem to do it a lot |

Thanks for the help guys I actually resolved this myself by lowering the voltage a touch and playing with my fan usage at certain temperatures making a curve with them in afterburner. To answer the question of exactly the 570's I got the stock cards.. the basic "reference" cards i dunno how to be more exact then that? they are not pre overclocked or anything or any special cooling. Umm I got them overclocked to the stat's i listed earlier with 1013 volts just kept backing down the voltage until it wasnt stable anymore and now the heat sits at around 88 celius max on the top card and 82 or so on the bottom card.

Got them stable with Furmark 15 min burn and 3d mark 11 got 12k video score on it with the over clock up from something like 1073 or so without the overcock

Thats hot, there are quite a few games (Diablo 3, Tribes Ascend, probably many others) that will just lock you at 99-100% GPU usage, so you can sustain temps like that for many hours, and you also have to take into account like 5-10c for ambient temperature changes and maybe more if your case ventilation is not amazing, if you are getting temps like that on max fan speed it is probably not wise to be overclocking stock cards that are SLI'd |

Negative the fans are not maxed out anymore the big thing I was running into was my voltage was alot higher then it needed to be to achieve that over clock. I backed it down and now the fans can control the temp to mid 80 to high 80 cel with arund 55% fan speed.. curious what is not "hot"? for this model card.. I heard a few sites claim 90 degrees was still well in acceptable limits for this style of card because they run "hot" im not expert so I will definitely back down my overclock and take advice I don't wanna flush my money down the shitter for a few extra frames per second on games for the most part i am maxing out just fine now anyways.. just trying to learn about overclocking and satisfy my curiosity as to what I can pump out of my computer.

88C is too hot. The cards will fail given enough time at that temp.
Perhaps OP just needs to clean them out. Blower cards are magnets for dust.
You want 78C or lower. That way you will have the cards forever basically.
@OP. This is what we mean. This is a fan card.

This is a blower card
![[image loading]](http://images17.newegg.com/is/image/newegg/14-130-595-Z03?$S300W$)
Blower cards have the fans turned vertical and angled to suck air in through the back of the card, through the length of the card, and out the back of the computer case. Blower cards are superior to fan cards where case temperature is a concern, however individually speaking a fan card is more capable of cooling that specific card.Last edit: 2012-07-24 09:30:32 |

I would say dirt is a possibility but I havent even used this computer for 4 months yet.. its very clean in my room and well I will blow the fans out regularly.. but hey.. ill just leave it stock for now and tinker with it some more tomorrow. Im sure there is something I am missing. Ill aim for the 78 or lower. Could be not possible unless I add some case fans which i will look into.. I have liquid cooling on my CPU and have it overclocked to 4.5g from 3.4g so we shall see.

How many case fans do you have? More would definitely be good here.
Also it is the summer time, so if your ambients are high, 82C and the like isnt all that bad anyway. But you want to try to average around 78C year round.Last edit: 2012-07-24 09:34:30 |

| SLI will just run hot even if you spent a bunch extra on a branded card with better cooling, you should be able to get lower temps with higher fan speeds though |

Cooling System Front: 200 mm fan x 1 Red LED on / off fan x 1 / 700 RPM / 19 dBA
(can be swap for 120 / 140 mm fan x 1)
Top: 200 mm fan x 1 / 700 RPM / 19 dBA (can be swap to 120 mm fan x 2 )
Rear: 120 mm fan x 1 / 1200 RPM / 17 dBA
Bottom: 120 / 140 mm fan x 1 (optional)
Side: 200 mm fan x 1 (optional)
(can be swap for 120 mm fan x 2)
Obviously I don't have the optional fans which i could upgrade later.. but yeah thats basically my fan set up. I have the big 200 mm fan on top and most of my case is practically ice cold to the touch even when im running burn tests. umm it doesnt feel like a hair dryer lol.

| You might have just gotten tough luck on the ASIC lottery then. GPU-z is capable of giving out ASIC ratings. Maybe explore that one day. I wouldnt look into them too hard though. |
