hey guys. im pretty sure the high pitch squeaking noise i get randomly is from a fan in my imac. it does it every 10 mins or so, squeaks 4/5 times then shuts up. apart from the slightly irritating noise (which i can live with) do you think there could be any underlying problems? i have no idea what a 'normal' istat read out is ment to look like. any help welcome.
