I think the problem first occured since I updated to 10.3.6 or the latest security update. Even in idle the fan is slowly spinning. I put the energy saving prefs to auto. does sb know this problem and have a clue?
I'm not sure if it does make any sense to reset PMU so I did not do that yet. Should I try?

Yes, either you have a application running in the background that is using up resources without you knowing it, or maybe just try resetting the PMU...
