ATI 4850 fan speed

So my comp came with a 4850, I like the card just fine, but when I check the ccc when the card is in idle the fan speed is 0 and the card temp is 61, when im playing WoW it's running at 24% and the temp is 81... It seems kind of hot to me, is this how it's supposed to run?

Is there a way for me to raise the fan speed and if I did would that affect the life of the card?

    A lot of newer graphics cards are coming in around 80-85C on stock coolers.


    You have a few options, first you can google Riva Tuner and download that, pretty sure it has fan speed profile support for the 4850 by now. If it doesn't or you don't want to use that tool you can also set up a fan profile manually:

    In Catalyst Control Centre, make sure clock and memory settings are correct and turn on Overdrive. Create a Catalyst Control Centre profile called "fanspeed". Navigate to C:UsersUserNameAppDataLocalATIACE and you'll find an XML file titled "fanspeed", open the file in Notepad or your preferred editor. The file should resemble the following:

    <Feature name="FanSpeedAlgorithm_0">
    <Property name="FanSpeedAlgorithm" value="Manual" />
    </Feature>
    <Feature name="FanSpeedRPMTarget_0">
    <Property name="Want" value="0" />
    </Feature>
    <Feature name="FanSpeedPercentTarget_0">
    <Property name="Want" value="65" />



    "65" is the fan speed % you want it running at, I read anywhere from 30% to 65% is good just depends on how loud it sounds to you. Also I think you have to select the profile whenever you reboot.


    Last option is you can buy an aftermarket cooler but you should be ok at least with a stock one at stock speeds.

    I used to have a dual 4850 crossfire setup, now I use a 4870x2. Here's my advice.

    The ATI 48XX runs really hot, the temps you mentioned are usual.

    If you dont have heat buildup issues with your system, ie crashes/reboots, or the cards heating up other overclocked components of your m/b like the Northbridge, dont tweak the fan speed. Leave it at auto.

    2 reasons for that (and that's from personal experience):

    1st) Noise, those fans spin with an annoying buzz. If you are not bothered by this, simple disregard.

    2nd) Make sure your fan speed keeps the card cool, because if you manually do it, the card may not be able to switch to the

    right speed if heat builds up suddenly since the manual tweak keeps the fan locked at a certain % regardless of temp.

    Finally, I would advise you to change the speed from the new Catalyst control center option and not from editing the file.

    My 4850 used to idle between 75-78 oC (top card) and 65-70 oC (bottom one) and peak at 85-90ish oC

    My case was carefully designed to ensure airflow (I just use an Antec 900, nothing fancy) and I never had problems with heat buildup.

    My 2 cents.

    Enjoy your cards :-)

    Aye almost all of the newer GPUs generates substantial heat.

    I always replace the standard fan with a bigger one.  Indeed its very noisy, but you would notice some temperature drop.  I feel comfortable if its 50s.  80s I feel nervous.

    So far, however, no one ever told me their PC shut down when GPU is running around 80.

    For the record, I have been using 1950 then 8800 then 4850.  Planning to upgrade soon for one of my PCs.
