This cooler claims to be compatible with the GTX 570. It takes up more than 2 slots on the motherboard, though. | |

I've also 2 GTX570's at a system (these two: EVGA GTX570). From the card in the first PCI-e slot i've removed the plastic casing for now (only for temporary) and placed one Gentle Typhoon AP-15 above the two slots. It differs around 15-20° Celsius between just only the card with his own fan or stripped version with an AP-15 @ ~1800rpm. | |

Oh great there are two evga 570 types it seems after i saw your picture. I have this one: http://www.evga.com/articles/00596/ | |

You could lower your GPU voltage and maybe clock speed as well to reduce power consumption. This doesn't improve cooling directly, but the fan will have an easier job. | |

Lower the voltage? I wish that would work :( Mostly on gpugrid the voltage must be raised by 0.025v to garantue an absolut errorless use over all type of workunits. I know that the voltage has a direct impact on the heat. I used long time on the 560ti 448 cores the standart voltage for longer time. Then a new workunit came on the plan and errors on this card until i raised the voltage on this card too. Since then i raise the voltage on every fermi card by this little amount. Buuut since i have remote control of my systems since two weeks i can react better On errors over weekends etc. So hmm. I can try to lower the voltage on the too hot card only but only tommorow because i have then a local access to the computer. Because yesterday while the initinstallation one of the gpus hardly hock (needed a ten seconds shutdown without powercord) because i changed to often the values like voltage, clocks etc. | |

Does your card ran clean with 93 degres? I have now 84-85 with 75 % fanspeed. I wish i could bring it back to 70% where the fan is much Quieter. Does a remove of the plasticcase always is a good solution with an aditional cooler? Because i think the cooler is build for such type of airflow. I will think about it ;) Does your case have good airflow? Is there a side fan blowing on the GPU? If not would a new case be an option (cheaper and perhaps better solution than an aftermarket GPU cooler)? I ask because those are very high temps. While I've never owned a GTX 570, I have run 2x HD 5870 cards with single GPU fans and the temps have never exceeded 65C running at 99% GPU even in the summer. BTW, did you get my PMs (here and at Einstein) with average WU times for my 2 HD 7850 cards? Thought you would want them for your excellent spreadheat since you did't have figures for the 7850. | |

The case is opend so the only airflow is the sometimes running AC. The card with the better cooling blows the air out on the side too (palit card), so the other (bottom) card perhaps suck in some warm air around too. I had not much time yesterday but i will try out some positions with a 8cm blower tomorrow perhaps i can kill the one or other degree With another position ^^ additional with the reset of the gpu voltage i can perhaps lower the cooler back to 70% so the card is silent again, hoefully without error the next months. | |

I would definitively suggest to add side fans blowing at the GPUs, there needs to be a cooler airflow between them. | |

I wish that would work :( Mostly on gpugrid the voltage must be raised by 0.025v to garantue an absolut errorless use over all type of workunits. If you lower both the Voltage and the Clocks you should be able to find a stable point. A 2.5mV reduction coupled with ~5% Core and GDDR reductions should be stable and sufficiently reduce the amount of heat the fans have to dissipate. Might be worth investigating until you improve cooling another way. Also, clean the heatsink and fan blades. ____________ FAQ's HOW TO: - Opt out of Beta Tests - Ask for Help | |

Another option for increasing airflow to GPU's would be a PCI slot cooler. | |

There is no end of crap out there, that will do little or nothing to cool anything, | |

Oookaaayy some skunk had closed the windows, so the room went hotter then i though. I looked now again after opening the windows for two hours and it gone from 84 down to 77 degress ^^ Man man man. I will try the hint to put two 14cm sideways to the gpus soon (plus it has a learning effect because all machines should run with two graphiccards in the future) because a single 8cm only warmed the card up because it suck in too much hot air from the card above, i had to remove it instantly. | |

Where would that slot cooler pull air from? It would suck heat produced by the GPU below and blow it at the GPU fans above... Useless. | |

Yes im not a fan of pci cooler too. | |

Another cooler to look at would be this one: | |

Oh great there are two evga 570 types it seems after i saw your picture. I have this one: http://www.evga.com/articles/00596/ Yeah I think there are some more fan/cooling types. EVGA has a lot of different cards... :P
Yes the WU's will run and finish successfully. I have my system placed on a benchtable... so when I open the window combined with max fanspeed @ the cards and the AP-15, it will work and cool directly. But I have to say I'm not happy with it at all, 77 degrees for a long time (120 hours a week or something) is way too hot and noisy. The maximum ambient temperature is ~25 degrees. So remove the casing helped this time with my coolerdesign, but I really dont know if it will work with your card.
Yes it is expensive... I agree with that. But when I've bought these cards from someone (second hand) I get also two fullcover WC blocks. The problem is: I dont have a pump, radiator, etc... so the cooling solution from above is hopefully only for temporary. ;-) But yes, I can understand your point... when I had to buy new WC blocks at this time it was also a no-go for me. Maybe you can look at some second hand cooling solutions. Often will it matter in price... | |

dskagcommunity, what about a 5 or 6 Euro PCIEx16 riser? | |

A veeryy nice idea but only this machine has not much space nearby. There is a tablefoot :-( | |
