All normal. they can get hot. When I use the i7 for 3D rendering it can heat the room. hint: don't lean on it or touch the top/back.
you can also use a macbook pro as a waffle-iron, yet it would still be in "normal" operating ranges.Quadra 700/PM 8600/G4 500/G4 MDD DP/TiBook/PowerBook/iMac i7, Mac OS X (10.6.3)

which would probably only happen if the Ambient room temperature is over 35°C and you were running the CPU at 100% for over an hour.
then it might overheat.Quadra 700/PM 8600/G4 500/G4 MDD DP/TiBook/PowerBook/iMac i7, Mac OS X (10.6.4)
I am not worrying about the temperature too much the top and back does get hot by the vent. But this shows that the aluminum is an excellent conductor and doing it's job and letting the heat escape via the casing and vent.27" IMAC I5, Mac OS X (10.6.4)
additionally, your imac would shut itself off if the temperatures would rise too high.
I think this is probably allowing a bit too much room for complacence. The real problem is what happens to components -- premature failure -- which are being slow roasted over the long term. The problem is the fans are not programmed to ramp up until, in my opinion, things get far too hot.
Depending on the room temp, I use smcFanControl to add a few hundred rpms or more (I have four or five settings.) I also stick with the default rpms if things are cool enough. Now that summer is finished on this side of the planet, I'm usually not far above those.

Well, people like to have their quiet computers, don't they. And I have to say, most of the time the iMac is very quiet.
Don't forget about dusting too. The vents don't do much if everything gets clogged up.24" 2.4 GHz iMac(10.5.8) MacMini(10.4.11) 2GHz G5(10.4.11) Airport Ext. (n), Mac OS X (10.5.8), 23" Cinema Display, Epson 836XL scanner, Epson R1800 Printer
