Caustic smell comes out of ventilation slot!
After a day or two since I first turned on the iMac 27" i7 a week ago, a noticeable strong bad smell started to come out from the left side of the ventilation slot behind the display as you see it from the front, i.e. the right upper corner as you see it from the back; I believe this is where the power adapter is situated. The smell resembles the way brand new iMacs smell but with a much, much stronger smell, from which you get a burning-caustic feeling in your eyes (imagine a very mild tear gas feeling).
Any ideas what it might be, what to do about it and to what extent I should be worried about it would be appreciated very much.
Thanks guys for the prompt answers.
I'm nowhere near an Apple store! The fumes still persist constantly till now, nearly ten days after purchase. Yes, burnt chlorine is a fair mach, I guess. No other problems. Running smoothly from day one.
Here are some temperatures and fan speed that the widget iStat Pro shows:
HD = 57˚
CPU = 46˚
Ambient = 22˚
GPU Diode = 60˚
GPU Headsink = 60˚
Mem controller = 52˚
Optical Drive = 49˚
Power Supply 2 = 67˚
Optical drive = 1000rpm
Hard drive = 1297rpm
CPU fan = 939rpm
Is this a good question?
