I found a helpful link that describes a very simple way of controlling your 4850/4870's fan speed. At default it is around 80 degrees which is a little too hot for some.
First Enable Overdrive in the Catalyst Control Center.

Next Create a new Profile using the Profiles Manager in the CCC and make sure Save All Catalyst Control Center Settings is checked.

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 - Thanks Spartan for the path...

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. Done.

It works like a charm for me. I set it to 50%, and the temperature now sits at 49 degrees down from 81 degrees.
 
Ah, I didn't know it was a repost. I was searching for a way to cool my card down on this forum earlier, but never found anything - which led to a google search bringing this up. That's why I posted it.

Sorry about that.
 
Just did a quick check and as I'm running Xfire with two 4850 cards, it appears the new fan profile is only operating on one card, the other is still at 81c.
Any ideas?

Edit: sorted it, the data for the second card is further down the list. That also needed to be altered as well. They're now both at 60c

I saw this too on hardocp and I have my fan set to about 32%, this puts it about 57C on idle and the noise level is barely audible, but anything above that I find annoying, even if the cooling performance is improved.
 
could do with a hand setting mine up cant find the folder specified :mad:looked where it says doing my nut in.

do you think this issue will be fixed when new drivers come out?also is there any progs i can use to lower the temp if i cant find the folder.
 
I got my idle temps down to 50 from 64 with fan on 30% :D

only downside is you cant use the AMD GPU tool so you are stuck with a max gpu at 790Mhz :mad:
 
The 4870 cooler is real good at 30%, even in game it wont top 75c at 30% so there is plenty of headroom for OC with the stock cooler just need to find the right combination of fan speed and noise that suits you.

C:\Documents and Settings\"Username"\Local Settings\Application Data\ATI\ACE for xp.

Make sure to save a profile in catalyst control centre first.

Idling 55C for me down from 70 something. :)
 
thanks for this, i was looking for a way to increase my 4870 fan speed.

i got mine at 50% and temps are at 51c while im gpu folding.

noise isnt too much of a problem for me as my delta on 5V is still louder:p

You also need to set view hidden folders in folder options/view.
 
Thanks. :) Set to 35% (will have to get used to the noise again as with the Zalman Watercooling my PC is quiet). But idle temps have dropped drastically and now I'm at 61ºC... result!

Nice one! :D
