    BFG 7800GT OC
    Dear All,
    I have a BFG Tech 7800GT OC, and I want to slow down its fans,
    because they are really loud, even when the computer is not in use.

    I have ForceWare drivers: 81.95, and the latest version of RivaTuner.
    This version has been known to be able to control BFG's 700GT OC.

    My motherboard is a BFG nForce4 called BFG RNF4U.
    I have also installed the lastest nForce drivers.

    When I slide the speed control tabs in RivaTuner, the speed doesn't
    change!

    What can I do?

    Thanks,
    Riddick

    2 more things I should perhaps say:
    1. might this be fixed in the next release?
    2. I have read as much documentation, stickies etc...
    I have posted on other forums first, so that I know that it IS possible
    to control this card, it just seem that I'm unable to.

    Riddick

    No, that won't be fixed in RT as it is not RT's issue.
    That should be fixed from ForceWare's side.

    thanks for your reply; do you think it is possible that this card is not controllable at all?
    I have installed both 81.94 and 81.95 and it doesn't work.

    Are you excluding a motherboard problem as well?

    Thanks for your time,
    Riddick

    Nope, it is the driver's issue.

    right - but why then is it possible that some other people with the same card can control it?

    I don't have NVStrap installed - is that OK?

    Thanks for bearing with me so far.

    Can someone help me? The fan is driving me crazy!

    How is it possible that other people can control the card and that I can't?

    Thanks,
    Riddick

    Hi,

    I have the exact same problem with a BFG 7800 GTX. It has a new revision cooler. It spins at 100% all the time. And there is a temperature sensor attached to the heatsink, so i don't get why it spins at 100 all the time. Ok, at idle my gpu is 34-35°, but the noise is crazy. I already emailed to BFG and I'm waiting for a decent answer....

    In the other topic there was a command line option, but it doesn't work, so I'm afraid BFG has altered something to the whole system. In the mean time, I'm going maaaad.

    what motherboard do you have? DO you think it's possible that they have
    plugged in the fan into a non-controllable power outlet?

    That's the worst thing. I actually have the card sitting in a Shuttle SD11G5. The thing is dead quiet, except for this card. I don't know what the problem is. The first answer from BFG was:

    We know it's a tad noisier than the first revision, but it cools better.... Tss.

    It's a special connector. I hope I won't have to cut and solder wires just to get the damn thing silent. I hope it can be done with software...

    Don't mess 7800 GT and 7800 GTX. These display adapters have absoultely different fan control approaches. GT uses reference PWM controller and separate 2D/3D fan speeds, GTX - temperature based external fan controller.

    Oh ok, thank you. But then why is my 7800GTX spinning at 100% when idling at 36°? Problem with the card, with the drivers?

    So what is the conclusion about my card?
    Can you give me a summary?

    So:
    - Is the motherboard is unrelated to the problem?
    - I know there are some people that are able to control this card

    May I ask how have you determined that it is running at 100%?

    The reason is driver. I won't repeat it third time.

    This is why I refuse to buy an nVidia card atm. They need to get their crap together. Having a gpu sound like a hairdryer is flat out stupid.

    I called BFG Tech support about it and all I got was 'that is how it is supposed to sound, it is a high powered card'. What a crock of ****. Wonderful service there....

    I'm glad to see Hilbert (and others) brought/bring up fan noise in his/their review(s) because only by jumping on them and criticizing them will they listen and fix it.

    Hmm, you got a good point there... But if that's not 100%, now I'm really worried.

    No, I mean, there's absolutely no variation in noise. Sounds the same at bootup, in windows, in games. It's subjective I know....

    No, you are right. I briefly had a GT and a BFG GTX with their new copper heatsink/fan and the fans spun the same 24/7. It sounded just like a mini hair dryer in my case. It was the most rediculous thing I have ever heard. The 6800 Ultra spins 100% at boot, then spins down in 2D, then spins back up relative to heat in 3D. Their 7800 series doesn't do that, and it is extremely frustrating to spend that amount of money and have to put up with something like that.

    Thank you... Ridiculous is the word. I bought the BFG card for 2 reasons:

    1: Their support that was superb (They only replied to 1 mail out of 3).
    2: Everybody told me it was quiet (ok, maybe the old cooler. This is madness).

    I spent over 500 euros for this card. If nothing can be done (the 15.8 unfortunately didn't change anything, but we expected that with the new cooler of course), I will have to sell the damn card and get another one.
