Welcome to Apple Discussions!
Do you have a 24" iMac with an ATI 4850? A recent firmware update became available for it, which may solve problems with that GPU:
If that's not the Mac do you have, please more clearly identify your Mac*:
So we can suggest the correct hardware test instructions, and then determine what is the cause. Also I suggest backing up your data*:
In event some troubleshooting risks your data.

As long as your iMac is running normally then yes it is normal for it to feel hot especially the back left hand side. The iMac has internal fans installed to keep it cool but you do want to be conscious of it's location and room temperature as it can affect how hot it gets. Make sure it's not in direct sun light and if it gets warm in your room or you have it in an enclosed space a small fan for the back might help. I have one of these behind my iMac: http://www.directron.com/arcticbreeze.html
Mine gets hot too but it gets a bit hotter when im using converters etc, this is idle temps now;
CPU A: 45c
CPU Diode: 54c
CPU Heatsink: 54c
HD Bay: 55c
Memory Controller: 51c
Northbridge 1: 61c
Optical Drive: 48c
Power Supply: 68c
CPU Fan: 1199
Hard Drive: 1725
Optical Drive: 797
Earlier today the Hard Drive Fan was over 2500 rpm and HD was 61c all others were high e.g CPU Diode 59c and Heatsink 58c and Power Supply 71c
I can just about put my finger on the top, im scared somethings going to melt!
Does that look normal too?
I came across this discussion and now I am worried about my mac. Mine gets really hot also. I just got it not even 2 months ago. I downloaded the iStat pro widget and my numbers or reading are:
HD Mac: 104 F
CPU: 162 F
Enclosure Base: 95
Enclosure Base 1, 2: 95
Heatsink A: 149
Heatsink B: 130
Exhaust fan: 6200 rpm

i agree, your imac runs quiet hot (cpu 73°), but this is in normal range when your are running several apps.
please look into "activity-monitor" and there all processes.
sometime the printer could leave a open thread and this may also cause heavy load to your cpu.
if no app is running, you should have about 98% inactivity.
