    Okay, here's the problem. I just received my HD 4850 3 or so days ago. And I've been running F@H GPU. Now the temps are up to 82C, but the damn auto speed controller or w/e its called that comes on the card. Is only running the fan at 31% which is pretty much 2200RPM. With a GPU load of 70+ percent.

    Now I'm not liking these temps at all, nor am I liking the fan controller. Can someone help me find a program that can controll the HD4850 fan?

    Well its not the auto speed controller that is the issue. Its the temps that ATi set as safe and the speed they thought would suffice. Currently there is no program that can control fan on these cards. Soon there will be rivatuner to do exactly that but not yet. You could just be like the rest of us proud 4850 owners and get an aftermarket cooler for it. I got the ThermalTake DuOrb vga cooler. As for those temps, they are well within operating temperature, but i agree that they are just too high for these cards.

    hope that ati mini-oven inside my case is also within m-audio's guide-line, and intel's guide-line, and western digital's guide-line and nec's guide-line and sirtec's guide-line and mushkin's guide-line and... you get the point

    I have the VisionTek 4850 and I got my temps to drop by unplugging the wire that controlled the fan speed on my card it was the blue wire but the fan is kinda loud.

    lol ya i bet it is loud. Ati set the fan speed for a reason ;) DuOrb is really quiet and cools well. not to mention it lets you only take up 2 slots unlike some aftermarket cooling

    if you make a profile in catalyst after turning on Overdrive( make sure clock and memory settings are correct). You can then go to the file "C:\Users\Bretware\AppData\Local\ATI\ACE\Bretware.XML. the xml file will have the same name as the catalyst profile you saved. right click and hit edit.

    <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" />

    Change the value to "manual" and Want value to "65"

    Save the file then reload your profile in catalyst.

    65% seemed perfect for me, 70% was loud but you may need it if your case has poor air flow.

    You will may have to select the profile everytime you start the computer, but it will work until there is a fix or better info so i can figure how to change the auto target temp.
    Good Luck ,bretware

    Amazing! Thank you very much! It worked perfectly, and within the first minute the temps dropped from 82C to 52C running on 70% speed (which isn't that loud)

    Problem is, when I tried 100% (just for ****s and giggles) after 20 seconds or so the fan started to buzz.

    Damn man, you're a Genius. Works like a charm but fan at 65% sounds like a hair dryer for me. I'll find something I can live with. I'll be spreading the word but giving you credit if you don't mind.

    I can't seem to get it to work. I make a profile but it doesn't appear in the folder, all i have is a file called profiles.

    edit: i've found it and it works :)

    Wow, well done bretware!

    Set mine at 65% and it dropped temps by 22C...

    You have to set "show hidden and system files" in folder options to view the profiles.
    Also, Unlock the overdrive setting ... if you haven't done so already.

    Edit... works after a reboot too!

    Great find mate!

    Works great, set 35% fan speed, idle's at 45-46c now.

    With the fan at only 35%, quite quiet, I loaded up FurRenderingBenchmark and set it for stability test, after 10 minutes temperature topped out at 81c. This is fantastic, especially for only 35% speed on a stock fan and running Fur benchmark. And this was with 790MHz on the core.

    For those of you who never ran Fur benchmark nothing hits a video card as hard as this.

    With all the hell we went through with the 3800 series with the fan speed and we could have just edited an xml file this whole time!!!???!!!

    Sorry about that, It will keep the settings with out having to reload the the profile on reboot.

    A few things about ati cooling,
    Fans running at the highest speeds can cause two problems, the first is virbration that can cause problems on boards that do not have a locking retainer. 2nd I've seen fan speeds about 80% and over tax some power supplys causing random shut downs.

    80c is way too hot!!!!!!!!, 80 degrees Celsius = 176 degrees Fahrenheit.

    Between 50c and 65c is what i'm getting(Fan at 50 now). 65c is where i draw the line.

    Should work with the 4870, but it would be better if i could get the auto target temp. working or a fix from ATI
