HD4850/4870 Fan Fix!



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(username)\AppData\Local\ATI\ACE \Bretw are. 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 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.

Ok my profile ive named "fanspeed" doesnt have a "fanspeedalgorithm" setting inside it

Can i just add it?

EDIT: nevermind, remade it and its a bigger file now, not sure what happened there but never mind

EDIT: wohoo its working

EDIT: down from 80oC idle to 49oC and still dropping

no more snow i guess?

Not yet, scared the crap out of me though fingers crossed it was just heat or a dodgy connection somewhere as once i reseated the card it was fine the whole card was scolding hot when i took it out though

I'll have to do a bit of a test run in something 3D now and make sure its all ok

EDIT: ive run furmark for 120seconds at 1920x1200 full screen and it hit a max temp of 72oC and no graphical glitches. guess all is ok now then crisis averted

Good stuff.
