    Anyone else with a gtx 280 has this issue where the fan stays at 70% -1300rpm after running a game?
    (On a fresh reboot it is at 40%- 700rpm)
    Measured using gpu-z.

    I saw this issue is known on the web, maybe a vga bios update might resolve this?

    Thanks!

    Does Riva tuner not work with 200 series yet, if so you could create fan profiles.

    For how long does it keep spinning at 70%? Maybe it's just trying to cool down your card and will eventually spin down by itself, when the card's cool enough, again.

    Otherwise, try tuco's suggestion.

    OK, thanks!
    actually it stays that way for a couple of hours
    I suppose a driver update will fix this
    but this card is so great that I hardly care about this...

    (I need to update my profile)

    RivaTuner 2.09 works just fine with the GTX280. I just slightly modified my fan profile to take into account that the non-load fan speed of the 280 is about 40% full duty cycle, as compared with the 880GTX, which had about a 60% non-load speed.

    Yes but how do you know the full load fan speed of the 280 and the medium load?
    Isn't it supposed to be regulated automatically by the card according to temperature?

    Don't know if it's connected but over on the overclockers forums there's quite a few people complaining about their GTX cards acting up. Like just playing a game ofr 5 minutes or running a benchmark suddenly causing the card to hit over 100 degrees and start to throttle. The fan is meant to speed up or slow down depending on the cards temperature so maybe you are having a similar issue. Some people think that some of the GTX batches have bad cores while others reckon Nvidia will fix it with a driver update.

    This got me really worried though as i've got my GTX 280 now but can't run it until my new case arrives sometime this week, hope the card ain't borked ><.

    In case you're worried about the card, why don't you just set the fan speed to 100% then?

    UPDATE:
    just installed forceware 177.40, and things begin to settle down,
    played crysis(all on very high:thumbup:) and now using gpu-z to monitor.
    The fan slowly goes to 50% so it is better. I beleive they will tweak this
    issue further in next drivers, and then the card will be perfect... I think it's worth every cent, especially compared to my previous 7950gx2:)

    If you read Hilbert's review of the 280 here at guru3d, he states that at heavy load the core temp goes up to about 85C. That's what the default automatic regulation will do for you. Personal preference, but that's too hot for me.

    The fan duty cycles are in %. So 100% is the highest, right? 40% seems to be the startup desktop speed which in my well ventilated case gives a core temp of 40C-45C. I scale the fan speed so that it reaches 100% around 78C.
    Fit a line between x1 = 40, x2=100, y1=45 and y2=78 and you can scale up the fan % (x) as the core temp (y) increases. I never need to know 'medium'.

    With my 8800GTX, I never got core temp above 75C. So far, with the 280, I can keep it below 70C at the heaviest loads I've pushed it at. You won't get that level of regulation with automatic fan control.

    Again, this is just my preference. I feel heat = short lifespan. I like having gpu's that don't artifact or die prematurely.

    nice idle temps, I get about 52c.
    I will try what you suggest but the drivers need to mature first.
    with the latest betas the AF and quality presets dont stick.

    same fan issue here

    same issue here, once the fan goes up to 75-100 % the fan will never (tested for hours) spin back... it stays there forever if you dont reboot your machine. you can stop all 3d applications but the gtx280 fan will stay at 100% till you are rebooting even when the card reaches 43C it is spinning at 100%... nice job nvidia... fix it fast, i paid 590 euro for this card, make it worth this price

    Just thought I'd mention that I don't have this issue on my GTX260's after playing a few games they both quickly went back down to 40% fan utilisation (700RPM). I guess its specific to the GTX280 or I'm just not effected.

    Did you try JerseySeven's advice? (in this thread)

    as of drivers 177.41 the issue still exists.

    it might be a hardware issue

    Well, finally I managed to tame the fan on the gtx 280 (Aka DA Beast),
    using the fan tweak guide in the rivatuner thread, and JerseySeven's advice.
    Simply created a few fan profiles.
    I hope future drivers or vga bios will resolve this though, as many 280's seem to be affected.
    Anyone else that solved this issue otherwise please post!:approval:

    How are you creating fan profiles exactly? I can't directly control 2d and low power 3d, only performance 3d. :3eyes:

    @JerseySeven:
    Did you try running the furmark, with 4xAA enabled? That should push your card to >100c

    GTX 280 and AMDx2 4800? Wow, what a HUGE waste of money.

    No offense m8, but you need a new processor and MB to take advantage of that card properly.
