Sapphire HD4870 Fan control?
hi,
I have in my computer with a Sapphire HD4870 1Gb installed.the problem is I want to reduce fan speed, it is not at that level for a reason.For nvidia i can use the EVGA precision tool to overclock and control the fan speed, is there a similar tool for ATI cards?
Re: Sapphire HD4870 Fan control?
Well there was ATI tool..but it does not work for the newer cards...so you will have to manually change it in the registry somewhere...

f 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.
