OP, have you looked at the 'Activity Monitor' to see if any processes (Safari) are maxing out CPUs?
Very not normal. You can try the reset PRAMs and SMC path but it sounds very unusual to me.
Even if you have one of your cores running full blast (there's an airport bug that does that) I don't think mine ever got that high.
I would exchange.
Update: Called apple and found out my product is defective and they are sending me a new iMac. Apple has great customer service.
I can't speak to the actual fan speed #'s, however, I can verify that the fans are indeed loud. I had a couple i5's previously - and the HDD's were very annoying, but I didn't really hear the fans. In the i7 I've used more recently - I notice the fan noise much more, and it is annoying too. But nothing when compared to the clicking of the i5 HDD.
Just got a 27' i7 iMac but noticed the fans were really loud. I downloaded iStat and got these for the fans.
Optical Drive: 3414 rpm
Hard Drive: 1097
CPU Fan: 3861 rpm
is that unusual? any solutions?
What did Apple say was defective? I have taken my 20" iMac into the Apple store 3 times for this same issue (CPU fan runs at max speed ~ 3800rpm) and they have not been able to solve it.
Any info you have would be great!
