Imac internal temperatures? To hot?

Hi, i just got the 21.5 inch imac a few days ago and i am worried about the temperatures. Here is a snapshot of them. Are they unnormal? I usually just run ichat, firefox or safari and itunes and the cpu temp is 45-48 degrees celcius. this is the screen shot of right now.S

I am not sure how to post a picture so i will just tell u what the temps are.
HD: 45
CPU A : 39
Ambient: 22
Memory controller:44
Northbridge:51
Optical drive:42
Power Supply 2: 57


btw this is all in celcius.

Not bad at all. Hot might be in the 90°C zone. But your temperatures are very average, if not below average.

Ok, thanks very much. When i called apple they said that the average is 10 to 35 degrees and that i should take it in to get it checked out. but now i dont have to worry. thanks.

If you would like, I have 2 Macs sitting in front of me, and another one across the hall (which is the same model as yours) I can show you the temperatures on those?

Ok that would be great.
