OpenSource ATI driver - Fan running at full speed all the time

I know this is a common problem and have read other topics but couldn't resolve. Anyways yesterday I found a solution - I have 2 graphic cards (hybrid) and they were both on. So I turned one off and installed Jupiter for power management and from there on the fans were quiet and I was happy as hell.

However (:)), yesterday evening I also updated the system and the fan and it's noise came back. I checked whether I am using only 1 graphics card and I am.

Maybe the problem is (false) temp reading from GPU?

The thing that is weird is that if I boot into Windows the fan is still at full power (previously it wasn't). Did I f--- up my hardware with software? :)

//OH, yes - I forgot to mention that my laptop is not hot at all. The temps are about 50°C.

This Ati fan control post worked for me in ubuntu and I also use this in Archlinux.
