Hello everyone,

So, with your guys' advice I built myself a new comp and happened to have purchased a ATI HD 4850 card with it.

Make no mistake, this card kicks major ass. However, it runs EXTREMELY hot and it causes my entire case to get extremely hot.

I saw a similar thread a page back regarding coolers you can buy for your graphics card (this one in particular). However, I wanted to ask if there was anyway that I can NOT buy something and get this thing cooled off.

Apparently there's a way to get the fan to spin faster, but when I followed that route my XML file for CCC did not include fan control settings.

Any suggestions will be lovely

Well here are the steps once again in case you need them:

Make a profile in catalyst after turning on Overdrive and make sure clock and memory settings are correct.

For Vista

Then go to the following location and open the following file for editing "C:\Users\Your Windows ID\AppData\Local\ATI\ACE\Your CCC Profile.XML. The xml file will have the same name as the Catalyst Profile you saved. right click and hit edit.

For XP

Then go to the following location and open the following file for editing "C:\Documents and Settings\Your Windows ID\Local Settings\Application Data\ATI\ACE\Your CCC Profile.XML. The xml file will have the same name as the Catalyst Profile you saved. right click and hit edit.

Now go down the page until you see the following lines in the XML file ...

<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Automatic" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="23" />

Change the "Property name="FanSpeedAlgorithm" value=" from "Automatic" to "Manual"

Then change "Property name="Want" value=" from "23" to your desired fan speed.

Save the file then reload the Profile you just edited in the CCC.

You will have to select the profile everytime you re-start the computer.

But, to change fan profiles permanently type C:\Documents and Settings\Your Windows ID\Local Settings\Application Data\ATI\ACE in the run box when you click start. You should see the ACE folder. After clicking on it you will see multiple profiles. Right click the one you created with overdrive enabled. Go to "open with..." and select note pad. The xml files will open in notepad. Scroll down to the fan settings. And follow the above steps to change the fields, and your fan should speed up the next time you go to the CCC and activate your profile again.

The article fails to tell you that you need to open the XML in note pad. It sounds wierd but it works. I OC'd my hd4850 and have the fan speed at 60% and it stays below 55 degrees celcius under load. Hope that helps.

just a noob

couldnt you just download the overclocking software from ati, and turn up the speed from there, more mature drivers are also expected to fix that problem

My friend just got one and had the same issue. He found out the fan speed was set only to 22%, and his temps were idling in the mid-70's. He turned up the fan speed to 90% and now he's hovering at an acceptable 42C.

Just go into Catalyst and change the fan settings, like grk said.

Indeed, I tried to do that before but with no luck, as my CCC profiles for some reason did not include the fan settings in the XML file. Adding them didn't work either.

I fixed it using RivaTuner. Thanks for the help anyways guys

mr_choung

riva tuner, done!
