My Macbook Air fan is really loud My fan is running really loud. I have tried resetting the SMC and it didn't work. I have no applications running and my mac is not hot. If you have any idea what is wrong please help me!
If the SMC reset did not work it seems likely it could be a hardware problem. I would guess it's going into a fail safe mode causing the fans to always run full speed. This could happen if a temperature sensor malfunctioned , I would recommend taking the system into an Apple Authorized Service provider.
