    Hey guys,

    I'm quite new in the community and i'm looking forwart to solving my problem with your help.

    Short description of my problem:
    When I start up my computer after initialising mb bios the graphic card's vent gets really loud. I'm not able to distinguish wether it's the fan speed or the fan is actually hitting something hard while turning. I looked at the card & fan very carefully, cleaned it, but the problem remained the same. When I login to my Win7 64bit after initialising CCC the sound sometimes disappear due to driver speed max of 40% fan speed.
    I googled for quite a time and discovered several posts where the vapor-x model had a bad bios which causes this problems, but I do not have a vapor-x! Further on this fan problem occured someway half a year after installation. So it wasn't there when I bought the card.
    I really think it could be a bios/driver problem, but i do have the latest drivers and it's really hard to get the so called latest working bios for your card. I tried several listet on this page, but I do not know if they are the right ones and with some i discovered "subsystemid" errors and so on...
    Maybe I'm not very into flashing, but it's really confusing for me to figure out what to do...

    I hope someone can help me! :)

    I will add a screenshot of my gpu-z.

    can you post a screen shot of the sensor tab on gpu-z?? my 2 5770's never did this. is it the long cooler or "egg" shapped cooler??

    your problem is your fan speed is set to 40% at idle so at load it will run like 80%. and at startup the fans ramp up high then should ramp down, but yours isnt. i can check your bios if you want to make sure it matches up with mine, older bios could cause this. just extract the bios using gpu-z zip the file/compress it and upload it.
    EDIT my fan speed at idle is 13% and my temps are about the same

    so in your bios your minimum dudty cycle for your fan is 35% that could be the problem, i can modify it to run lower at idle and the same at load if you would like before i do that, can you maybe get some sort of audio of what exactly it sounds like??

    I definitely run out of vocab to describe the sound, because I'm not a native speaker, but I'll try. ;)

    It doesn't sound like a fan which is at 100% speed. I checked the "right" fan sound in windows when the "bad" one was gone by manually speeding the fan up to 100%. It's definitely different.
    Actually it sounds like the fan is hitting something, but there isn't anything. I double and triple checked any material issues. But the noise is definitely louder than just air flow!

    I hope this description helps a little bit and I apologize my bad "nerd-english" ;)

    I'm Austrian btw! :cool:

    p.s.: I have to admit that I once (very pissed because of bad hardware) forced the fan to stop going crazy with my finger and the noise was gone!

    sounds like MAYBE one of the fins on the fan is broke or cracked thus causing it to not spinn flat but wobbly thus creating a nasty sound. if you have a spare case fan break a fin off it and plug it in, does it sound the same?? ill try and find a video or something depicting the sound, @ VON_KAIN if it aint broke dont fix it

    no it doesn't .but my gpu runs hotter than denise milani (ie 80~85-90c )
    and the thing i hate the most until now is that the fan is really really stupid on auto.
    itruns mostly 41c @40% fan and that's idle on the full throtle goes 85c@50% fan.
    stupid fan.
    i also see that the opencl is off to my card.

    k, i'll check the fan gain.
    but i think it would help to adjust speed percentages as you mentioned.
    it would be great when you would upload the modified bios and a short "what to do/how to flash" list! ;)

    thank god! :)

    @overclocking101: you mentioned editing my bios would "help"! I'm not able to detect any damage to the fan, so would you be so kind to modify mine or send me yours/a working one with fan speed adjustment. And maybe a short "how to do it right" description! ;)

    thx alot :)

    85c Is very high for the card at stock clocks, my 5850 at full load only lets around 65c with fan on 45%

    update:

    I think "wobbling" describes the sound best when my fan tries to go into normal status after initialising CCC in win 7 ultimate 64 bit. If I don't log into my win the "full speed annoying sound" remains the same.
    I think I have to get a new cooling/fan or should i buy a whole new card?

    @ overclocking 101: i think my temperatures are very good and consistent so the cooling is on duty. maybe you can send me a modofied version of my bios to tune down my fan speed at startup to get rid of most of the sound! THX :)
