The difference between this issue and others I encountered along the way is the lid opening thing.Does anyone know if getting the lid past the 90 degree mark triggers anything?The other theory I have is that there's some dust blocking the intake and when the lid is opened wide, the air is somewhat obstructed by the bottom of it. Updated to 10.7.4searched every discussion I could find on this matter. If I get it back the fan returns to normal functioning.What I did:checked the temperature sensor values, they are finechecked for crazy background tasks, there are none, CPU usage is at max 7%it does the same thing even in safe modereset PRAMreset SMCreinstalled OS X (Lion). It only does it when I open the lid more than 90 degrees. No system processes consuming high CPU, just idling.There's a twist to this issue, though. My Macbook Pro (13', early 2011, Core i5 2.3) started to behave weird, its fan (only the exhaust one, since it's a 13' Macbook Pro with the Intel HD integrated graphics) is running at top speed (6200-6208 rpms) with no reason at all.
