GTX570 Fan Won't Change/Increase

    I've recently had problems while playing games where the whole system crashes. After touching the video card and realizing it was much too hot, I decided to monitor (with SIW) the temperatures while playing games and sure enough, they rise to over 100 C. At the same time, I'll check the fan speed and it'll be in the range of 80% (correct), but the actual speed is 1140 RPM (25% default). I've updated the drivers of my GeForce GTX 570 card (version 337.88) and no change.

    I decided to disable nVidia's GeForce Experience software and manually attempt to change the fan speed. I installed both MSI Afterburner and EVGA Precision to manually control the fan speeds (using one at a time, so there are no conflicts). When doing so, I'll get temporary lapses of having control for 5 - 20 minutes, then it goes back to the 1140 RPM default. Note that the speed will be what I set it (~80%), but the fan speed doesn't adjust to the correct revolution count, and remains at 1140 RPM. I also tried setting fan speed curves, and there is no change.

    The behavior of it all is interesting as well. Sometimes the fan speed does adjust without any problems, both in manual and auto (as well as curves). These periods last from a few minutes to about an hour. When the system does seemingly decide to set the GPU's fan to 1140 RPM (25%), it stays at that regardless of what settings I change (via Afterburner or Precision). That period lasts from 10 minutes to an hour, after which I have control again. The card's fan is capable of running at full speed and operates faithfully when it does. There are no airflow issues and it has been running in its current configuration and location for two years (ie. no system component changes). Because of this, I believe the issue is software-related. Whether that is in the operating system or the graphics card firmware, I'm not sure.

    When playing a game, the GPU's temperature slowly rises to 100 C, at which point I exit the game so that it can cool. It appears to get up to around 110 C before the system crashes - but I don't want to test that limit too often. As stated before, when the fan does open its control, it can operate at full speed no problem. Before looking at the hardware issues, are there any software related things that could be causing this?

    I've attached a couple of screenshots to illustrate what is happening.

    Exhibit A: When the GPU's fan is in "no control" mode, it doesn't matter what the fan speed is set to. It spins at the minimum 1140 RPM.

    Exhibit B: When the GPU's fan is in "allow control" mode, I can adjust it at will and the real speed (RPM) updates.

    Has anyone else had similar problems? Afterburner and Precision are nice, but is there a deeper level to look at and change variables associated with the card's fan? Any help would be fully appreciated. For system specifications, see the following:

    Anyone here have any suggestions? I can't think of any other possible causes to the problem or a solution.

    Soo if i understand this correctly your fan allows for manual control but doesnt want to work in auto? If so then just create a fan profile in afterburner and set it something like - for each 5c the fan spins 5% faster.

    Hi Scatler. Sorry if my original post was unclear. The fan doesn't work correctly for either the manual or auto modes. Instead, it had random times where it works (manual or auto) and random periods where it doesn't work (manual or auto). When the later is the case, overheating occurs. I just can't figure out what it cuts out intermittently like that.

    Darn. Honestly, to me it seems as if the fan itself is hitting the bucket, but i might be wrong. You could try and get a replacement fan if that's even possible or gouge the fan out and ghetto mod some sort of replacement or get a new cooler altogether.
    Anyways that's just my 5 cents, wait and see what others might suggest.

    Odd...to me that does not seem to be a driver issue but a physical issue with the card because the fan is still moving during this whole time frame. To me this sounds like the fan controller on the card has malfunctioned/burning out because if its reading 80% and randomly ramping up and down there is a problem with the two being in sync.

    Most likely, the best solution I can think of is the card is defective and needs to be RMA'ed to EVGA as their warranty should still cover it. But its most likely a bad fan controller on the card at least thats what I think (It could be driver related but the way its happening just seems to me to be that problem).

    Thats my opinion.

    This exact same thing has happened to me on my GTX660 but only in the last week or two. I refuse to believe it's just a coincidence that our fan speed controllers are both bad. If I leave Afterburner off and let the GPU run it's own "auto" mode, then the fan speed scales using the GPU's default values but if I try to set them - no dice. It will work at random for a few minutes but then stops.

    If i turn the fan speed to 85% it immediately revs up:

    The second i drop it down to 84% it goes to 0 RPM

    Doesn't make any sense to me...
