If i run my fans at max with "macs fan control" then my cpu temps stay around 55-62c. however, if i don't use the apps and let apple defaults take natural control, the temps hit 80c and the fans don't rev up automatically. why could this be? i installed "smc fan control"and "Macs Fan control" , are they somehow affecting fan even when closed? i'm thinking of taking it into the repair shot to have a look. i shouldn't have to use fan software. it should work naturally. plus, i worry about my fan wearing out running it at max all the time.
