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.

Everything in that istat status looks normal to me. Maybe you have a faulty fan. I'd definitely take it in - since it's only likely to get worse over time. These things aren't really user serviceable - especially since yours is still under warranty.

And since there are three fans in an iMac, it's best to let the genius bar open it up and determine which one is making the noise.
