    whoops, i meant to use the word 'reference', http://ak.buy.com/PI/0/500/208280331.jpg i think this is the ati reference design?

    i would just extract the bios, change the minimum fan to 35% from 50%, flash it, & never think about it again, no software no incompatability no problems

    RBE to edit the bios, gpuz cant edit i dont think, only extract

    http://www.techpowerup.com/rbe/

    it's from the same site/people as gpuz anyway

    then you flash with winflash (apparently risky, i used it while overclocked :nerd: ) or atiflash in dos

    Just tried winflash. Pressed Program. After 10 minutes of nothing I had to hard reset...

    Why the hell can't I change the fan speed like I used to do so easily? :bang:

    EDIT: i just remembered, after 12.2, some dll that 3rd party apps use is missing

    so you just need to get it & fan control should work

    i think it's atipdlxx.dll & atipdl64.dll, put them in sysWOW64 & system32 respectively

    take them from a pre 12.2 driver, keep the newest installed

    completely forgot about this :giggle2: no need for the thread to have dragged on for 2 weeks

    Hey guys, I have the exact same problem, although this didn't help. What did I do wrong? I installed an old catalyst driver, 9.1 copied the two dll files to my desktop, installed the newest catalyst 12.6 and copied the dll files back to System32 and SysWOW64 but nothing happens. Restarted - still no difference. What am I doing wrong?

    There was a particular version of sapphire R700 cards, with a custom heatpipe cooler that had faulty hyper aggressive fan settings, and sounded like a jet engine all the time even when in idle.

    I know, I had one...

    Sapphire released a bios update that fixes it. I wonder if you have the same card by chance (blue pcb, and it doesn't report the VRM temps either) ?

    And if so...is this why you are trying to lower it...

    Actually my card is a Gainward Radeon. And I'm pretty sure it's a software issue, as it doesn't occur with older drivers (eg. Catalyst 9.1 from early 2009).

    you're talking about trying to use 3rd party apps right, this wont help the limit in CCC

    which reminds me, arent some CCC limits written in an xml file? i remember people unlocking the range of the mhz sliders... maybe the same can be done to fan

    Hey kn00tcn

    Thanks for your reply. Actually I'm not talking about using 3rd party apps, I tried exactly what you suggested: copying those two files... Apparently it helped badigel, but I had no success, I still can't go below 50% fan speed in CCC or any other 3rd party app.

    What did I do wrong? Could you maybe explain the procedure a bit more detailed?

    Many thanks in advance! :)
