Hi !

Which IC on the card is resp. for the Fan regulation on a 5850 Extreme from Sapphire ?

The Fan continuosly runs at 100% and cgminer doesnt even show the RPM just 85% and it goes down to 0% but then Fan is still running at full speed.

I cannot even control the fan with aticonfig, it is constantly spinning at full power.

Its strange that not even the RPM can be read, temperature is fine though..

Anyone got an idea which IC on card is responsible for the regulation ? I had a quick look and saw nothing special ..

Thanks

oc
