Then the system reboots. The GPU'S get to about 70C then system reboots. Anyway to Cool them down? I have x2 Ge force 285's OC. I tried Putting SLI on so it would just run 1 GPU but it still over heated. | |

This machine can reach well over 20k Rac. If i can get the video cards cooled down. | |

70 is no where near the max temp for any GPU. It must be some other component of the computer overheating/failing. | |

I tried Putting SLI on so it would just run 1 GPU but it still over heated. Are your video cards in adjacent slots? try separating them by 1 slot and also use a 120mm fan near the front aiming toward the back. it sounds like they are in a 'hot spot' in the case and there is insufficient air flow to keep the ambient temperature cool enough. A machine like that will need at the minimum 90 to 120cfm air flow out the back and top. There is no such thing as 'quiet'fan operation for this powerhouse. Which case do you have? What size power supply do you have? Insufficient power can cause random reboots too. Also, 70C is considered warm not hot for these vid cards so there may be a motherboard setting that is set improperly as well such as too fast a pci-e bus speed. It is not impossible to have some bad ram in one of the video cards. Try running one at a time to see if one of the cards is causing this. If one at a time does not cause reboot for either card, then it may point to a probable insufficient power supply especially if anything is overclocked. Do not overlook PopandBob's advice. He has given solid recommendations. ____________ | |

I didn't see any mention of it in your post, so if you can set that to a higher %, that could bring the temp down too. ____________ | |

The cards are sitting right next to each other. And the Fans are going at 1725 RPM at about 60-70C. When i get home ill try moving them apart. Ill keep you posted. | |

It has a 1600 Watt PSU I have a Thermaltake Speedo with 15 Fans modded in it.(Including 2 230MM Fans one on side and on TOP. Motherboard is a ASUS Rampage 2 Extreme. | |

That Mobo has 3 PCI-E but only 2 of them are PCI-E 2.0. The other is a PCIE-E 16x normal. How much of a performance decrease do you think ill be looking at? | |

How much watts is your PSU really supplying? Sounds like every time I try to run a card like that without upgrading PSU I have to underclock undervolt to prevent machine turning off at random. This indicates voltages (particularly 12v bus) are at or near spec limits. | |

LOL...

Haha there is no dust everything just came out of the BOX new! | |

LOL... That does seem low, mine is 1.23v. What cpu? Hehe yeah I literally once a month give my workstation a complete 'bath' along with air-blow out of all heatsinks everywhere and thorough vacuuming, remove case fans and clean fins etc. It is amazing the junk they pick up! Every 2 months I remove my cpu cooler (Zalman 9700N which gathers dirt like it was a magnet!) to clean the lower fins that nothing can get to since they are circular and the bottom fins are positioned such that little can get through besides an air-blow from the front. Unfortunately this wastes thermal compound since I have to clean and re-apply every time I remove it, but my machine runs nice and cool in a hot florida environment so I have no complaints. ____________ | |

So.... my GPU's fans where only going at 40%. I cranked then to 100% (Loud as hell) but has been running stable for 1 hour now (Crosses Fingers) | |

The fans on my 295's are at 100% all the time. | |

oh yea..there's that... | |

oh yea..there's that... does auto fan work in your 1060? mine says auto but i never see the speed change. when it boots its manual so i set it via the driver. ____________ | |

same same...Always used manual set to 100% so not really thought about it. I think it may have worked with 182.50 Quatro drivers? Cause I just recently discovered it no worky now; thought it odd and wondered if always been that way. | |

Before anyone decides their CUDA card lacks auto fan control, you need to let it get over 74C or more. My GTX295 and GTX285 cards sit at 40% fan until the temp gets up towards 80C, then the fans slowly increase in speed. For example, the two GTX285 sweltering in my new build are running at 82C and 79C, respective fan speeds (on auto, exactly as new out of box) are at 58% and 47%. | |
