Can't change GPU Fan Speed

Hello guys,

This is my first post here, and sorry if I'm not in the right section.

Well, today I've been trying to change the default fan speed of my (very good............!) GTS 250, because when I play BF3 it hits a nice 70-75 celsius, but I couldn't.
I've tried RivaTuner, but when I click ''Apply'', the speed would turn back to 35% where it's stuck.
The thing is, that even when the system is really hot , the GPU's fan speed doesn't go above 55 %.
I've also tried MSI Afterburner, but while it, and GPU-Z showed that the speed had changed,I couldn't hear any difference.
The last thing I tried, was reinstalling all NVIDIA drivers and then using the NVIDIA Control Panel + System Tools, but that gave me a BSOD.

Maybe the BIOS doesn't allow any changes?

Finally, I have one more question (a little off-topic):
When I'm playing heavy games, like BF3 the PSU gets pretty hot.
Is that normal?

Thanks a lot for your help and time, and sorry for such a big thread.

  1. you might need to up the fan speed before every gaming session

    Thanks for your fast reply.
    This is what I'm trying to do. But I can't. And that's why I'm asking for help
  3. so you cant change it like 5 minutes before gaming or go to the program and change it right before gaming
  4. I can't change it at all!
  5. oh didnt see the stuck part of the original post and sorry i really cant help you because i mostly have amd cards
  6. Please read my first post.
    Thanks
  7. Ok, no problem!
    Someone else will be able to help me
    Anyway, thanks for your time
  8. if i could man but im more experienced in amd card and thanks for understanding
  9. Don't worry, no problem!
  10. What GTS 250 is it?
  11. A Gigabyte one. Sorry I couldn't replay earlier
  12. *reply
  13. Have you tried Gigabyte's software for that card? Easy Boost, I think, but I'm not sure. I'm not even sure if it has a fan control function, but it's worth a shot.
  14. No, but I'm gonna try it. Thanks
  15. Just tried Easy Boost - no luck. I put the fan to 100 %, and , even though Easy Boost and GPU-Z say that the fan speed is 100 %, it is exactly the same as before.
    Please help!!!

    Thanks

    Well damn, that was my one arrow to shoot at this situation. I figured the software that was actually meant for the card would have the best chance of working, but I guess not.

    Well, have you tried EVGA Precision?
  17. No, I haven't .
    I think that, since both Evga Precision and Msi Afterburner are based on RivaTuner, they are almost the same.
    Is there any other way to force the fan run at full speed when I need that?
    I experience low fps in games because of overheating.

    Thanks

    Yeah, I didn't think about the RivaTuner connection, but you're right.

    I really don't know of any other way besides editing the VBIOS to make it stay at 100% (or however high you want it), but that's not really what you're looking for. There may be settings in the VBIOS for the auto speeds too, but I'm not sure. That's an extreme thing to do though, that may, of course, brick the card if you get it wrong.
  19. Well, I don't want to risk bricking my lovel
    I've found that while intense gaming, the fan speed changes. Maybe some setting in BIOS prevent any changes?
  20. *lovely card!
  21. Also, I have the exact same situation with this guy :

    http://www.tomshardware.co.uk/forum/276996-15-cannot-change-speed
  22. I've been playing a match of BF3 now, and the card hit 64 celcius (not too bad), and the fan's maximum speed was 43 %. I suppose that because the card didnt go up to 75 celsius, the speed doesn't need any adjustment.

    Please tell me what you think.
    Thanks
  23. Sorry for the late(er) reply, but anyway, yeah, this is definitely strange, and it does basically sound like the same problem as in the post you linked. The good part at least, in your situation, is that the speed doesn't seem to be completely frozen at a single speed and the temp isn't too bad (very good, actually).
  24. Thanks for your reply
    Well, As for the fan speed, I think that what is happening, is that I can see it,but something is preventing me from changing it.
    But if the temps are actually good, what do you believe causes the frame drops I experience after some time in game?
    Finally , is the PSU supposed to get hot after hours of heavy gaming?

    Thanks a lot for your help
  25. Not sure what's causing the framerate drops, honestly. If the temps are as good all the time as you posted, then it's definitely not temperature related.

    I suppose it could be a combination of a relatively weak card and a relatively weak CPU (by today's standards).

    And it's OK for the PSU to get warm during gaming sessions, yes, but it should never get truly hot. If it does, you're probably pushing it close to its limits.
  26. Yeah, this is what I thought at first. But then, I noticed that in the first 30 minutes, the game runs pretty well @ 40 fps, but then , the drops start- the fps counter says that I have 20-25 fps.
    As for the PSU , it actually gets pretty hot, but I don't think I get it to its wattage limits.
    Thanks
